The security database on the server does not have a computer account for this workstation trust..
We have a single Site single Domain (xyz.com) which contain following 3 Domain Controllers: 1- DC1 (PDC, windows server 2012 R2, a hyper-v virtual server) 2- DC2 (Secondary DC, windows server Ent 2008 sp2, physical server) 3- DC3 (Secondary DC, windows server Ent 2008 sp2, a vmware virtual server) Problem: The error message "The security database on the server does not have a computer account for this workstation trust relationship" is coming while end users attempting to change their password who are controlled by a domain password policy. Action Taken: 1 When i chech the computer account, i found following result: C:\Windows\system32> NETDOM VERIFY computer_name The secure channel from computer_name to the domain XYZ has been verified. The connection is with the machine \\DC3.xyz.com 2 Then i do force to RESET the secure channel to DC1: C:\Windows\system32> NETDOM RESET computer_name /domain:xyz /server:DC1 3 After restart the computer, user able to change without any error message!!! Now My Question is: Why the error message "The security database on the server does not have a computer account for this workstation trust relationship" appear while those computer's secure channel is connected to DC2/DC3 only? Why those client computer's Secure Channel is automatically registered to either DC2 or DC3?
Idle time out GPO for Remote Desktop Services sessions not working in Windows 2019 servers
I have configured GPO to Set time limit for active but idle Remote Desktop Services sessions. Policy has been set to disconnect sessions which are idle for more than 3 hours. But I am getting warning after 30 minutes itself. This GPO has been applied at OU level. Issue occurs only with Windows 2019 servers. Session time limits on Windows 2016 servers which are in the same OU works well. I ran gpresult /h on the affected servers. I could see session time limit policy is applied properly still sessions are getting disconnected after 30 minutes. Anyone came across this issue? Please assist me
I can't Turn on network discovery
Hi Why in Advanced sharing settinggs the Turn on network discovery can't save the settings in Windows Server 2019 Preview? Although as an admin I turn it on and save settings, it's again off when I open Advanced sharing settinggs.

What's the correct procedure to install .NET 4.8 on Server 2019 without breaking anything else? Thanks a lot
Announcing Windows Server Preview Build 26257
Announcing Windows Server Preview Build 26257 Hello Windows Server Insiders! Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions, Annual Channel for Container Host and Azure Edition (for VM evaluation only). Branding has been updated for the upcoming release, Windows Server 2025, in this preview - when reporting issues please refer to Windows Server 2025 preview. If you signed up for Server Flighting, you should receive this new build automatically. What's New Windows Admin Center (WAC) Beginning with build 26252, Windows Server 2025 preview customers can download and install Windows Admin Center right from the Windows Server Desktop using the in-OS app that takes care of downloading and guides you through the installation process. Note: You must be running a desktop version of Windows Server 2025 Datacenter or Standard preview to access this feature. Delegated Managed Service Accounts (dMSA) A new account type known as delegated Managed Service Account (dMSA) is now available that allows migration from a traditional service account to a machine account with managed and fully randomized keys, while disabling original service account passwords. Authentication for dMSA is linked to the device identity, which means that only specified machine identities mapped in AD can access the account. Using dMSA helps to prevent harvesting credentials using a compromised account (kerberoasting), which is a common issue with traditional service accounts.

Cleaning up WinSxS Directory to reduce space Windows Server 2012 R2
Hi I'm trying to reduce the amount of drive space taken up by Windows on my servers C Drive - currently the entire drive is taking up 28GB of a 30GB drive... I've used the disk clean up tool that ships with Windows but it didn't identify anything that could be removed (really!)... The Windows Directory is taking up 17.5GB of the 30GB drive so a big chunk. I've seen that you can reduce the size of the WinSxS directory within Windows which is currently taking up about 8GB, and this director (given it's size) seems a likely candidate for size reduction. I found this tool - but it is not compatible (won't install stating incompatible) - see: https://support.microsoft.com/en-us/help/2852386/disk-cleanup-wizard-addon-lets-users-delete-outdated-windows-updates-o Perhaps there's another tool I can use? Alternatively - perhaps there is something else I can do to reduce the data on my drive...? I'm working an a Windows 2012 R2 Server running off an EC2 Instance on AWS. Any help most appreciated? Thanks MarkAnnouncing Windows Server Preview Build 26252

Hi all. I have a Windows Server 2019 VM (HyperV) where I setup my first DC. I also setup DNS and DHCP on the server. After deploying these, the yellow warning icon appeared on the network icon in the bottom right corner, and it says "No internet access". Indeed, Internet access seems to be working normally. The only issue is the DNS sometimes unable to resolve certain random domains. It seems that unbinding IPv6 from the NIC almost solved this issue, but the warning icon and the No Internet message remains. I tried the troubleshooting tool. It is unable to diagnose the issue, and suggests a network reset. I did it twice, but it did not change anything. I took a dump of the network packets when the diagnostic tool is run, but I see nothing unusual. It finally connects to http://www.microsoft.com:80/ which I think is the normal way to determine if Internet is available. The server responds 200 Ok and some codes. I don't know where to look further. My ipconfig /all: Windows IP Configuration Host Name . . . . . . . . . . . . : SrvApp19 Primary Dns Suffix . . . . . . . : psw.local Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : psw.local Ethernet adapter Ethernet: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft Hyper-V Network Adapter Physical Address. . . . . . . . . : 00-15-5D-00-78-03 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 10.0.0.112(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 10.0.0.254 DNS Servers . . . . . . . . . . . : 127.0.0.1 NetBIOS over Tcpip. . . . . . . . : Enabled I attach one of the diagnostic reports.
