Server 2025 Core ADDS DC, Network Profile Showing as "Public" and not as "DomainAuthenticated"
OS: Windows Server 20225 Standard Core (no GUI), build 26085.1 Role: ADDS, DNS ForestMode: Windows2025Forest DomainMode: Windows2025Domain Platform: Hyper-V guest When standing up a clean Windows Server 2025 using server core and configuring it as a domain controller, the network category (profile) always shows as "public." A clean load of Windows Server 2022 with server core as a domain controller has the same behavior. However, in Server 2022, the fix is to add DNS as a required service to the nlasvc (Network Location Awareness) service. Once that is done, the network category reflects "DomainAuthenticed" and persists between reboots. In Server 2025, the nlasvc service does not have the same requiredservices as Windows Server 2022, and it does not start automatically. Even after configuring the nlasvc service the same way it is in Server 2022 and adding DNS as a required service, the network category still reflects "public." The only way to get the network category to properly reflect the "DomainAuthenticated" status is to disable and reenable the network adapter after each reboot.Announcing Windows Server 2019 Preview Build 17623
Hello Windows Insiders! Today we are pleased to release the first build of the Windows Server 2019, our next Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience as well as Server Core in all 18 server languages, as well as the first build of the next Windows Server Semi-Annual Channel release. What’s New in Windows Server 2019 Build 17623 For every preview release, we will provide a focus area that we would like you to take a look at and provide us with feedback on. We encourage you to try out any functionality in the release and we welcome your feedback. Validation for every preview: There are two major areas that we would like you to try out in each preview release and report back any issues: In-place OS Upgrade (from Windows Server 2012 R2, Windows Server 2016) Application compatibility – please let us know if any server roles or applications stops working or fails to function as it used to Extending your Clusters with Cluster Sets “Cluster Sets” is the new cloud scale-out technology in this Preview release that increases cluster node count in a single SDDC (Software-Defined Data Center) cloud by orders of magnitude. A Cluster Set is a loosely-coupled grouping of multiple Failover Clusters: compute, storage or hyper-converged. Cluster Sets technology enables virtual machine fluidity across member clusters within a Cluster Set and a unified storage namespace across the "set" in support of virtual machine fluidity. While preserving existing Failover Cluster management experiences on member clusters, a Cluster Set instance additionally offers key use cases around lifecycle management of a Cluster Set at the aggregate. Windows Defender Advanced Threat Protection We provide deep platform sensors and response actions, providing visibility to memory and kernel level attacker activities and abilities to take actions on compromised machines in response to incidents such as remote collection of additional forensic data, remediating malicious files, terminating malicious processes etc. If you’re already using Windows Defender Advanced Threat Protection (ATP), preview these features by simply installing the latest preview build of Windows Server, and onboard it to Windows Defender ATP. Otherwise, sign up for the Windows Defender ATP trial on Windows Defender Advanced Threat Protection. Windows Defender ATP Exploit Guard Windows Defender ATP Exploit Guard is a new set of host intrusion prevention capabilities. The four components of Windows Defender Exploit Guard are designed to lock down the device against a wide variety of attack vectors and block behaviors commonly used in malware attacks, while enabling enterprises to balance their security risk and productivity requirements. Attack Surface Reduction (ASR): A set of controls that enterprises can enable to prevent malware from getting on the machine by blocking suspicious malicious files (e.g.: Office docs), scripts, lateral movement, ransomware behavior, and email-based threats Network protection: Protects the endpoint against web-based threats by blocking any outbound process on the device to untrusted hosts/IP through Windows Defender SmartScreen Controlled folder access: Protects sensitive data from ransomware by blocking untrusted processes from accessing your protected folders Exploit protection: A set of vulnerability exploit mitigations (replacing EMET) that can be easily configured to protect your system and applications To deploy a default set of Exploit Guard policy on Windows Server, you can run the following cmdlets: Set-MpPreference -EnableControlledFolderAccess Enabled Set-MpPreference -EnableNetworkProtection Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 75668C1F-73B5-4CF0-BB93-3ECF5CB7CC84 -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 3B576869-A4EC-4529-8536-B80A7769E899 -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids D4F940AB-401B-4EfC-AADC-AD5F3C50688A -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids D3E037E1-3EB8-44C8-A917-57927947596D -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 5BEB7EFE-FD9A-4556-801D-275E5FFC04CC -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids BE9BA2D9-53EA-4CDC-84E5-9B1EEEE46550 -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 92E97FA1-2EDF-4476-BDD6-9DD0B4DDDC7B -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids D1E49AAC-8F56-4280-B9BA-993A6D77406C -AttackSurfaceReductionRules_Actions Disabled Add-MpPreference -AttackSurfaceReductionRules_Ids 01443614-cd74-433a-b99e-2ecdc07bfc25 -AttackSurfaceReductionRules_Actions Enabled $url = 'https://demo.wd.microsoft.com/Content/ProcessMitigation.xml' Invoke-WebRequest $url -OutFile ProcessMitigation.xml Write-Host "Enabling Exploit Protection" Set-ProcessMitigation -PolicyFilePath ProcessMitigation.xml Windows Defender Application Control Windows Defender Application Control—also known as Code Integrity (CI) policy—was released in Windows Server 2016. Customer feedback has suggested that it is a great concept, but hard to deploy. To address this, we are building default CI policies, which will allow all Windows in-box files and Microsoft applications, such as SQL Server, and block known executables that can bypass CI. The package contains an audit version and an enforced version. If the server doesn’t require additional drivers/applications, you can deploy the enforced version. Otherwise, you can use the audit policy, check uncovered executables, and then merge them into the default CI policy. To deploy the default code integrity policy, run the following commands: Copy-Item C:\CI\ServerDefault-EnforcedCI.bin C:\Windows\System32\CodeIntegrity\SiPolicy.p7b Reboot the server to allow code integrity service to load the policy. Failover Cluster removing use of NTLM authentication Windows Server Failover Clusters no longer use NTLM authentication by exclusively using Kerberos and certificate based authentication. There are no changes required by the user, or deployment tools, to take advantage of this security enhancement. It also allows failover clusters to be deployed in environments where NTLM has been disabled. Shielded virtual machines: Offline mode, VMConnect and Shielded Linux support You can now run shielded virtual machines on machines with intermittent connectivity to the Host Guardian Service by leveraging the new fallback HGS and offline mode features. Fallback HGS allows you to configure a second set of URLs for Hyper-V to try if it can’t reach your primary HGS server. To see how this can be used in a branch-office scenario, see Improved branch office support for shielded VMs in Windows Server, version 1709 on our blog. Offline mode allows you to continue to start up your shielded VMs, even if HGS can’t be reached, as long as the VM has started successfully once, and the host’s security configuration has not changed. (To enable offline mode, run the following command on the Host Guardian Service: Set-HgsKeyProtectionConfiguration –AllowKeyMaterialCaching.) We’ve also made it easier to troubleshoot your shielded virtual machines by enabling support for VMConnect Enhanced Session Mode and PowerShell Direct. These tools are particularly useful if you’ve lost network connectivity to your VM and need to update its configuration to restore access. These features do not need to be configured, and they will automatically become available when a shielded VM is placed on a Hyper-V host running build 17040 or later. For customers who run mixed-OS environments, we now support running Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server inside shielded virtual machines. Try it out—Create a Linux shielded VM template disk—and send us your feedback in the Feedback Hub. Encrypted Network in SDN Network traffic going out from a VM host can be snooped on and/or manipulated by anyone with access to the physical fabric. While shielded VMs protect VM data from theft and manipulation, similar protection is required for network traffic to and from a VM. While the tenant can setup protection such as IPSEC, this is difficult due to configuration complexity and heterogeneous environments. Encrypted Networks is a feature which provides simple to configure DTLS-based encryption using the Network Controller to manage the end-to-end encryption and protect data as it travels through the wires and network devices between the hosts It is configured by the Administrator on a per-subnet basis. This enables the VM to VM traffic within the VM subnet to be automatically encrypted as it leaves the host and prevents snooping and manipulation of traffic on the wire. This is done without requiring any configuration changes in the VMs themselves. Try it out—Configure Encryption for a Virtual Subnet—and send us your feedback in the Feedback Hub. Software Defined Datacenter If you are using Storage Spaces Direct, take a look at performance history for Storage Spaces Direct. Performance history for Storage Spaces Direct Administrators of Storage Spaces Direct can now get easy access to historical performance and capacity data from their cluster. Did CPU usage spike last night? When did this drive become slow? Which virtual machine used the most memory last month? Is network activity trending up or down? The cluster is pushing 1,000,000 IOPS – is that my new record? Previously, you’d need external tooling to answer these questions. No more! Previously, you’d need external tooling to answer these questions. No more! Beautiful new charts in Project Honolulu (and new PowerShell cmdlets, for those so inclined) empower you to answer these questions.

Known issues In‑place OS upgrade: Domain Controllers. During an in-place OS upgrade, Active Directory (AD) Domain Controllers (DC) might not be upgraded correctly. So, back up any AD DCs before performing an in-place OS upgrade. Editing or creating policies for AppLocker can cause the MMC snap-in to crash when generated rules for a packaged app. After upgrading the operating system, the AppX database may have corrupted entries, which causes problems for components that use those entries.

After a fresh installation of Windows Admin Center 2410, I cannot add any servers, clusters, PCs etc. WAC gives me "You can add this computer to your list of connections, but we can't confirm it's available" when I enter a computer name (either of FQDN or computer name alone). When I change to the Search Active Directory tab, I get: "We can’t search Active Directory because the Windows Admin Center computer isn’t joined to an Active Directory domain. It’s also possible that your account doesn’t have permission to read from Active Directory." The account I use is a domain admin, and the server running WAC is definitely joined to the AD DS. The server had the previous version of WAC installed where everything worked. Now, with the new version, that's no longer the case...HOW-TO: Import Out of Band Updates to WSUS using Microsoft Edge Chromium IE Mode and PowerShell
----- I recommend using https://www.powershellgallery.com/packages/Import-WSUSUpdate Full instructions to install the module are located here - https://www.ajtek.ca/blog/the-new-way-to-import-updates-into-wsus/ ----- History: 09/12/2023 - adding PowerShell method to the OP 07/30/2023 - please follow the latest comments for the updated approach using PowerShell. The method in the OP has become obsolete 01/13/2022 - update links and clarification to prevent an error "This update cannot be imported into Windows Server Update Services, because it is not compatible with your version of WSUS", added Troubleshooting and Q&A section. 02/11/2021 - initial version PREREQUISITES: Windows 10 / 11 / Windows Server 2016 or later with WSUS RSAT Tool installed. latest Microsoft Edge installed, version 97 as of time of writing. Internet Explorer (mode) is installed in Settings > Apps > Optional Features or equivalent location in Windows 11 HOW-TO: - Open Edge 97 or later - Open Microsoft Edge Options > Default Browser - Change "Allow Sites to be reloaded in Internet Explorer Mode" to 'Allow' - Add links to add to Microsoft Edge IE Mode - Remove all other links in the scope of *.catalog.update.microsoft.com, only these shall remain for the catalog.update.microsoft.com page. https://catalog.update.microsoft.com/ https://catalog.update.microsoft.com/v7/site/Home.aspx see screenshots below for better illustration. - Close Edge and all catalog tabs if there were any open, especially if you use "Open tabs from the previous session" feature - Open WSUS MMC and right click Updates from the tree > Import Updates - The link in Edge should open in IE mode, there are several indicators on this the open tab to point to https://catalog.update.microsoft.com/v7/site/Home.aspx?SKU=WSUS&Version=10.0.xxxxx.xxxx&ServerName=YOURSERVER.CONTOSO.LOCAL&PortNumber=8531&Ssl=True&Protocol=1.20 NOTES 1.When the link opened in importing updates from WSUS MMC does not contain the "v7/site/" part or does contain a https://www.update instead of https://catalog.update your configuration is wrong. 2. The "Default" setting will not be sufficient to allow the installation and use of the ActiveX plugin. Go back to your update catalog tab, Install the ActiveX if you have not done on this box already. Check if you have not setup restrictions to execute or install ActiveX plugins in IE directly or via group policy. 3. Edge now has the ability to an IE Mode button. Also it has a new feature to automatically add pages to the exception list. Do not use this ability as shown in the picture for this use case as it might add wrong exceptions to the list. 4. When there are wrong exceptions in the exception list for IE mode it might not work correctly and cause a missing but very important redirection, which ultimately cause the import to fail. More troubleshooting assistance below. LINKS STARTING FROM DECEMBER 2021 / JANUARY 2022: Links to add to Microsoft Edge IE Mode https://catalog.update.microsoft.com/ https://catalog.update.microsoft.com/v7/site/Home.aspx TROUBLESHOOTING: Q 1: Microsoft Edge does not allow me to configure any IE Site Mode links (greyed out). A: Either you have not enabled "Allow Sites to be reloaded in Internet Explorer Mode" to 'Allow', or your enterprise has set policies to prevent that. This should be clearly indicated by a lock and message in the Edge settings tab. Q 2: I have followed this guide or a previous version. I can see the cart to import into WSUS but cannot import any or just specific updates. Others fail with a message "This update cannot be imported into Windows Server Update Services, because it is not compatible with your version of WSUS". A: This is a "known" issue and the guide has been updated to reflect this issue and a potential change on the server-side. Please make sure only the two links are included in your IE mode list. They may not include www in the link name. You need to include both links, not just one or the other as in the previous version of this guide. Q 3: May I use the new Edge feature in Settings > Appearance > Internet Explorer Mode button A: I would recommend to refrain using this feature, as the mechanism between WSUS update import and the browser is extremly picky. It would not work if you just copy the same link into a browser tab. The feature of the cart to import into WSUS will be likely missing and you can just download to the Download folder instead. Q 4: Edge offers me to restart this tab in IE mode next time. A: you should not receive this message, otherwise the exceptions as stated in the guide are invalid or you have more than the stated links in place. Go through the guide again and double-check. Do not use this otherwise nice feature. It will cause to add more catalog links to the exception list which will cause an issue to import updates to WSUS, as described in Q #2. Thanks for the hint Eric_VanAelstyn, thanks to abbodi1406 for additional hints after this guide got invalid a redirection change in December 2021 / January 2022. cc AriaUpdated MissyQ cc for the other teams as I did not want to repost it in Edge and Servicing communities, unless you insist 🙂Azure üzerinde Windows Server 2022 Datacenter Preview deneyimi (tr-TR)

Most Common Mistakes in Active Directory ...
Here are some useful links to help you avoid making these common mistakes with Active Directory... Most Common Mistakes in Active Directory and Domain Services – Part 1 – MEA SI Blog https://blogs.technet.microsoft.com/meamcs/2018/12/31/most-common-mistakes-in-active-directory-and-domain-services-part-1/ Most Common Mistakes in Active Directory and Domain Services – Part 2 – MEA SI Blog https://blogs.technet.microsoft.com/meamcs/2019/01/08/most-common-mistakes-in-active-directory-and-domain-services-part-2/Active Directory Advanced Threat Hunting - Tracing the cause of account lockouts and password errors
Dear Microsoft Active Directory friends, In this article we are going on a "search for clues" :-). In the life of an IT administrator, you have certainly often had to reset a user's password or remove an account lockout. Now the question arises on which system the account was locked or on which system the password was entered incorrectly. In order to determine this information with PowerShell, some preparations must be made. "Advanced Audit Policy Configuration" must be configured in the group policies. This article from Microsoft provides a good starting point: https://learn.microsoft.com/en-us/defender-for-identity/deploy/event-collection-overview In my example, I have adapted the Default Domain Controls Policy. Before we begin, here is some important information about MITRE techniques: Account Access Removal: https://attack.mitre.org/techniques/T1531/ User Account: https://attack.mitre.org/datasources/DS0002/ Brute Force: Password Spraying: https://attack.mitre.org/techniques/T1110/003/ Account lockouts are logged in the Windows event logs with the ID 4740. We will therefore focus on this event ID first. The start of the PowerShell script looks like this: #Prep work for lockouts, Account lockout Event ID $LockOutID = 4740 #Find the PDC (Get-ADDomain).PDCEmulator $PDCEmulator = (Get-ADDomain).PDCEmulator #Connect to the PDC Enter-PSSession -ComputerName $PDCEmulator #Query event log Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $LockOutID } #Parse the event and assign to a variable $events = Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $LockOutID } #Examine some properties $events[0].Message #Regex? $events[0].Message -match 'Caller Computer Name:\s+(?<caller>[^\s]+)' $Matches.caller #Cool, but not as easy as: $events[0].Properties $events[0].Properties[1].Value #For all events: ForEach($event in $events){ [pscustomobject]@{ UserName = $event.Properties[0].Value CallerComputer = $event.Properties[1].Value TimeStamp = $event.TimeCreated } } #And we'll make that a function Function Get-ADUserLockouts { [CmdletBinding( DefaultParameterSetName = 'All' )] Param ( [Parameter( ValueFromPipeline = $true, ParameterSetName = 'ByUser' )] [Microsoft.ActiveDirectory.Management.ADUser]$Identity ) Begin{ $LockOutID = 4740 $PDCEmulator = (Get-ADDomain).PDCEmulator } Process { If($PSCmdlet.ParameterSetName -eq 'All'){ #Query event log $events = Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $LockOutID } }ElseIf($PSCmdlet.ParameterSetName -eq 'ByUser'){ $user = Get-ADUser $Identity #Query event log $events = Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $LockOutID } | Where-Object {$_.Properties[0].Value -eq $user.SamAccountName} } ForEach($event in $events){ [pscustomobject]@{ UserName = $event.Properties[0].Value CallerComputer = $event.Properties[1].Value TimeStamp = $event.TimeCreated } } } End{} } #Usage Get-ADUserLockouts #Single user Get-ADUser 'jesse.pinkman' | Get-ADUserLockouts Now we come to the incorrectly entered passwords. These events are logged in the Windows event logs with the ID 4625. #Prep work for bad passwords - Event ID $badPwId = 4625 #Get the events from the PDC $events = Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $badPwId } #Correlate the logon types $LogonType = @{ '2' = 'Interactive' '3' = 'Network' '4' = 'Batch' '5' = 'Service' '7' = 'Unlock' '8' = 'Networkcleartext' '9' = 'NewCredentials' '10' = 'RemoteInteractive' '11' = 'CachedInteractive' } #Format the properties ForEach($event in $events){ [pscustomobject]@{ TargetAccount = $event.properties.Value[5] LogonType = $LogonType["$($event.properties.Value[10])"] CallingComputer = $event.Properties.Value[13] IPAddress = $event.Properties.Value[19] TimeStamp = $event.TimeCreated } } #Bring it all together in a function Function Get-ADUserBadPasswords { [CmdletBinding( DefaultParameterSetName = 'All' )] Param ( [Parameter( ValueFromPipeline = $true, ParameterSetName = 'ByUser' )] [Microsoft.ActiveDirectory.Management.ADUser]$Identity ) Begin { $badPwId = 4625 $PDCEmulator = (Get-ADDomain).PDCEmulator $LogonType = @{ '2' = 'Interactive' '3' = 'Network' '4' = 'Batch' '5' = 'Service' '7' = 'Unlock' '8' = 'Networkcleartext' '9' = 'NewCredentials' '10' = 'RemoteInteractive' '11' = 'CachedInteractive' } } Process { If($PSCmdlet.ParameterSetName -eq 'All'){ #Query event log $events = Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $badPwId } }ElseIf($PSCmdlet.ParameterSetName -eq 'ByUser'){ $user = Get-ADUser $Identity #Query event log $events = Get-WinEvent -ComputerName $PDCEmulator -FilterHashtable @{ LogName = 'Security' ID = $badPwId } | Where-Object {$_.Properties[5].Value -eq $user.SamAccountName} } ForEach($event in $events){ [pscustomobject]@{ TargetAccount = $event.properties.Value[5] LogonType = $LogonType["$($event.properties.Value[10])"] CallingComputer = $event.Properties.Value[13] IPAddress = $event.Properties.Value[19] TimeStamp = $event.TimeCreated } } } End{} } #Usage Get-ADUserBadPasswords | Format-Table #Single account Get-ADUser administrator | Get-ADUserBadPasswords | Format-Table I hope that this information is helpful to you and that you have been given a good "little" foundation.
