Why did IIS ApplicationHost.config file disappear?
Hello, Currently, I am operating two cloud-based instances of Windows Server 2012 and 2016. In IIS, when I try to add a binding or modify the application pool, the changes are not saved, and I encounter the following error: C:/Windows/system32/inetsrv/config/applicationHost.config Error: Cannot write to the configuration file. When I navigate to the specified path, the applicationHost.config file does not exist. Additionally, for the Windows Server 2016 instance, there are no backup files available in C:\inetpub\history\. Would anyone be able to provide insights into the possible cause of this issue or suggest a solution? Thank you in advance for your help.
Hyper-V: How do VMs communicate with external?
Simple scenario: VM --> vNIC --> vSwitch (external) --> physNIC --> physSwitch The vNIC assigned to the VM has MAC address aa:aa:aa:aa:aa:aa, the physical NIC (physNIC; the vSwitch of type external is connected to it) has bb:bb:bb:bb:bb:bb. What mechanism ensures that when the VM sends a network packet to the external network (the physical network connected to the physical switch physSwitch), the MAC address of its vNIC (aa:aa:aa:aa:aa:aa) is used, and not the MAC address of the physNIC (bb:bb:bb:bb:bb:bb)? In other words: what makes physSwitch "see" aa:aa:aa:aa:aa:aa when the VM communicates to an external endpoint?
Untagged VLAN - Server 2025 Hyper-V
Hi, I have a strage issue and not finding a solution. Using Server 2025 with two node Hyper-V cluster. Most of the machines using VLANs which works fine. Some machines using no VLAN config. Which usually means the "Access VLAN 1" regarding our switch configuration. With Server 2019 this worked fine. With Server 2025 same NIC port, same server/NIC hardware "Untagged" VMs don't get any network connection. If I add a second NIC to the VM "Untagged" the NIC get immidiatly an IP address and has a proper connection. If I remove the first NIC, the second NIC stop working. It looks like something has changed with Server 2025 (maybe already with Server 2022). Do you have any idea what kinde of problem I have found? Thanks Jack
Launching EXEs on File Server Slow on Hyper-V Host
We have a Server 2019 Hyper-V host that hosts a Server 2008 file server (yeah, I know, too old) and other virtual machines we use as work stations that access various EXE files on the file server. Recently, (not sure when it's started) launching EXE files stored on the 2008 server from one of the workstations (all on the same host) is getting delayed, sometimes as long as 20-30 seconds. An odd thing is that when you first log on to the work station and run the EXE it starts in what I think is a reasonable time, until now a second launch would be a little faster, I'm assuming due to caching. But not, launching it a second time gets the delay. Other file types seem to be OK. Opening large PDFs, for instance, does not have the problem. Working on a virtual machine hosted on our OTHER, older 2012 R2 Hyper-V host (yeah, again, I know) and going across the network, host to host, to access those same EXE files never has the delay problem. Because of virtual machines the 2012 host not having the problem, I'm thinking there's something on the 2019 host that's been updated. Update history shows KB5052000 installed in February and KB5050182 in January. I see that the January update mentions "Remote Code Execution" but the info seems to be specific to Visual Studio so I'm not sure that would apply. Has anyone seen this behavior or can maybe give me a clue as to where to start even looking? Thanks, KenServer 2025 Highlight Selection Color
Just loaded Server 2025 Standard for the first time to play around with it. Did all the updates, installed VM Tools. Is there a bug in the highlighted selection color in Computer Management? When you highlight an object from the Local Users and Groups and Shared Folders, it's a bright blue highlight and the text is yellow. Anywhere else, the highlight seems to be the usual soft blue and white text color. Is that happening to anyone else? Went back to check a 2022 VM and it's not a problem.Windows Server 2022, IIS & Docker Container

Getting Prompted for Username and Password on Internal Web Site, HTTP Error 401.2 - Unauthorized.
I have an internal web site that uses Windows Authentication. This works perfectly on my Microsoft Windows Server 2022 Datacenter Azure Edition which is my developer server. When I tried to put this site out on our test Microsoft Windows Server 2022 Datacenter Azure Edition, with the exact same setup, I get prompted for my Username and Password. It does not matter what I have tried to enter for Username and Password, nothing is ever accepted and it I hit cancel, I get the dreaded HTTP Error 401.2 - Unauthorized. I don't understand why this would work on 1 server, but not the other server. HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers.Applications settings lost when publish website (Windows Server 2022 IIS)
Hi everyone, I've set up a Windows Server 2022 to host multiple websites. However, every time I publish a new website via FTP using Visual Studio, the application settings configured on the site disappear. I'm wondering if I'm missing something in my setup. Should I be configuring the sites differently, or is there a way to prevent these settings from being reset during deployment? Any advice or insights would be greatly appreciated! Thanks!Where do I configure this? Windows Server is consuming more than 50.000000 %
Windows Server is consuming more than 50.000000 % of physical memory, which exceeds your configured threshold. I'm getting this alert on a server that still has 90GB RAM free. I cannot find anywhere in Windows Admin Center to actually configure this. I found a post on this forum that has this same subject, but it's solution does not seem correct in my case. When I check the parameter set as the solution, mine is set to 0.10, which I guess is 10%. But it should be 0.50 if it's the correct parameter. And the solution sets it t a whole number. So it makes even less sense.

Affected products: Windows Server 2022, Windows Server 2025 Azure Local 21H2, Azure Local 22H2, Azure Local 23H2 Network ATC Dear Community, I have seen numerous reports from customers running Windows Server 2022 servers or Azure Local (Azure Stack HCI) that Live Migration settings are constantly changed to 1 per Hyper-V Host, as mirrored in PowerShell and Hyper-V Host Settings. The customer previously set the value to 4 via PowerShell, so he could prove it was a different value at a certain time. First, I didn't step into intense research why the configuration altered over time, but the stumbled across it, quite accidently, when fetching all parameters of Get-Cluster. According to an article a LCU back in September 2022 changed the default behaviour and allows to specify the live migrations at cluster level. The new live migration default appears to be 1 at cluster level and this forces to change the values on the Hyper-V nodes to 1 accordingly. In contrast to the commandlet documentation, the value is not 2, which would make more sense. Quite unknown, as not documented in the LCU KB5017381 itself, but only referenced in the documentation for the PowerShell commandlet Get-Cluster. Frankly, none of the aren't areas customers nor partners would check quite regularly to spot any of such relevant feature improvements or changes. "Beginning with the 2022-09 Cumulative Update, you can now configure the number of parallel live migrations within a cluster. For more information, see KB5017381 for Windows Server 2022 and KB5017382 for Azure Stack HCI (Azure Local), version 21H2. (Get-Cluster).MaximumParallelMigrations = 2 The example above sets the cluster property MaximumParallelMigrations to a value of 2, limiting the number of live migrations that a cluster node can participate in. Both existing and new cluster nodes inherit this value of 2 because it's a cluster property. Setting the cluster property overrides any values configured using the Set-VMHost command." Network ATC in Azure Local 22H2+ and Windows Server 2025+: When using Network ATC in Windows Server 2025 and Azure Local, it will set the live migration to 1 per default and enforce this across all cluster nodes. Disregarding the Cluster Settings above or Local Hyper-V Settings. To change the number of live migration you can specify a cluster-wide override in Network ATC. Conclusion: The default values for live migration have been changes. The global cluster setting or Network ATC forcing these down to the Hyper-V hosts based on Windows Server 2022+/ Azure Local nodes and ensure consistency. Previously we thought this would happen after using Windows Admin Center (WAC) when opening the WAC cluster settings, but this was not the initial cause. Finding references: Later the day, as my interest grew about this change I found an official announcement. In agreement to another article, on optimizing live migrations, the default value should be 2, but for some reason at most customers, even on fresh installations and clusters, it is set to 1. TLDR: 1. Stop bothering on changing the Livemigration setting manually or PowerShell or DSC / Policy. 2. Today and in future train your muscle memory to change live migration at cluster level with Get-Cluster, or via Network ATC overrides. These will be forced down quite immediately to all nodes and will be automatically corrected if there is any configuration drift on a node. 3. Check and set the live migration value to 2 as per default and follow these recommendations: Optimizing Hyper-V Live Migrations on an Hyperconverged Infrastructure | Microsoft Community Hub Optimizing your Hyper-V hosts | Microsoft Community Hub 4. You can stop blaming WAC or overeager colleagues for changing the LM settings to undesirable values over and over. Starting with Windows Admin Center (WAC) 2306, you can set the Live Migration Settings at cluster level in Cluster > Settings. Happy Clustering! 😀

Windows Server 2022 or 2025 Data Centre edition- concurrent editing of Microsoft office documents
Does Windows Server 2022 or 2025 Data Centre edition provide real time collaboration or concurrent editing (through workspaces etc) by multiple users on Microsoft office documents hosted on it locally. So for the sole purpose of having concurrent editing feature of office documents, can Windows Server 2022 or 2025 Data Centre edition become an alternative to using Sharepoint server hosted locally or on premise.Can't add shared servers, disappear after reload
I tried importing through the UI and as long as I don't refresh the page they show up under Shared on the main screen, but as soon as I refresh the site or try to open it in a other browser, none of the imported shared servers show up except for the Gateway server that hosts the website. Is there a limit in the amount of servers that can be added in WAC v2.4.0? I'm trying to load 157 servers from a csv file and haven't been able to properly import them as shared servers. Format of CSV that imports without errors: "name","type","tags","groupId" "servername","msft.sme.connection-type.server","tag1|tag2|tag3|tag4","global" I started the PowerShell route to see if I had any more luck with that, but then ran into this AccessKey issue (other thread) when using NTLM. Any one else ran into this issue and found a way to add so they stay and show up for others? Cheers, Edwardfeature Installation Error
