WAC vMode fails validating SMB
Hi Reviewing vMode and try add a Hyper-V 2025 (non hyperconverged) cluster with a FC SAN. Fails on Validating "SMB port accessibility". Have gone through firewall settings and opened all neccesary ports that i can find mentioned. Even tried without FW turned off without any success so hit the wall now. WAC vMode is installed on a vm running Win2025std and in same domain as the cluster (and hosts) i try to add. Probably some obvious thing i have missed so any suggestions?
No way to import shared connections WAC 2.6.4
hello, reaching out to to see if I am missing anything with the import-wacconnections change in the powershell module. Previous versions i had everything scripted and running smoothly where I could scrape AD for servers and tags and then import as shared connections for other engineers to use. Now, despite being a gateway admin, if I try and import a CSV via the windows admin center gui, I get an error that only personal connections can be imported. if I use powershell, despite providing the generated access token, I get a 403 error. my issued PKI certificate is good, I am a gateway and server admin, I even corrected the errors in the powershell module regarding $credential vs $credentials that copilot spotted Any advice or pointers to push forward?How to managed Active Directory using Windows Admin Center
Hello, Can I manage Active Directory using Windows Admin Center ? If yes, please provide the link to give me the documentation on the same. I can see that the Active Directory extension is in preview stage: https://docs.microsoft.com/en-us/windows-server/manage/windows-admin-center/use/manage-servers#active-directory-preview but this document is dated 2019. Any help on the above mentioned is appreciated. Thanks Sushanth AminUnable to get Windows Admin Center v2 (2410) to work at all
So I had the old Windows Admin Center installed and working, using Windows Credentials in my domain. There were a few issues with some of the menus that just would not work like they should, but normal updates to Windows Admin Center would fix it for a little while. They release Windows Admin Center v2 and I do an install of that with the old Windows Admin Center still installed. I am able to use the existing cert and could log into Windows Admin Center and see all the machines. Though after the Windows Admin Center v2 install, always got a ajax 500 error, when trying to connect any machine with Windows Admin Center, even the local machine. This past week, uninstall Windows Admin Center off of the Windows 11 computer that I had been using, both the v2 and v1 versions of it. I then reboot and install the Windows Admin Center v2, using custom setup. Prior to this I went into certificates on the computer and requested a web server cert for this computer using the name of the computer in DNS. My AD CS provided the new cert and I installed it as a computer certificate, under personal. Afterwards I then assigned Network Service full control of the certificate. I selected that certificate during the Windows Admin Center v2 setup and selected Windows authentication, and left everything else as default. Windows Admin Center installs and I launch it, I get to the prompt for username and password from Windows, enter the correct domain credentials and it repeatedly loops through. I went 17 tries and was never able to get into Windows Admin Center. Never got anything saying that I couldn't login, just repeatedly ask for the credentials. So how do I get this blasted thing to work? Uninstall it again, install the Windows Admin Center v1 then the v2 and try and deal with the ajax 500 issue? Nuke the entire computer and install it from a fresh Windows 11 install? Or just give up and always use remote desktop to manage all the servers, which Windows Admin Center v1 helped me half avoid?Register-WACLocalCredSSP: Failed to register CredSSP session configuration.

The SSL certificate contains a common name (CN) that does not match the hostname.
I'm after a bit of assitance for the WAC 2025 deployed in Azure. The fundamentals are setup, and I can add standalone servers, however when I add the hyper v cluster or the nodes underneath individually, and connect, it throws up the following error. There's a self signed cert bound to the cluster listener and verified working, but it still throws the below. I'm not sure what i'm missing. The cert is also in the personal store of the local nodes with their SAN within that same certificate bound to the listener. cluster.domain.com node1.domain.com node2.domain.com Connecting to remote server name.domain.com failed with the following error message : The server certificate on the destination computer (name.domain.com:5986) has the following errors: The SSL certificate contains a common name (CN) that does not match the hostname.

[msft.sme.remote-desktop v4.30.2] RDP extension fails to load in WAC 2.4.1
Description Product: Windows Admin Center v2.4.1 Extension: Connect to a server or PC via Remote Desktop ID: msft.sme.remote-desktop Version: 4.30.2 Authors: Microsoft License: MIT Issue: When attempting to launch the Remote Desktop extension, the UI never renders (infinite spinner) and the browser console reports: Uncaught SyntaxError: Unexpected token '<' In addition, certain .js module requests return HTTP 403, and the loader falls back to “null” instead of the correct main.<hash>.js. Steps to Reproduce: Install or enable the msft.sme.remote-desktop extension (v4.30.2) on WAC 2.4.1. Open WAC in a modern browser and navigate to Remote Desktop. Press F12 → Console and Network tabs. Observe: The <base href="/modules/msft.sme.remote-desktop/"> page loads, but subsequent scripts (main.<hash>.js) resolve to “null” or return 403. Console errors Unexpected token '<' Remote Desktop never initializes. Expected Behavior: The RDP extension UI should load normally, register its translation tables, and allow launching a remote session without syntax or module‐loading errors. Impact: Cannot use the built-in Remote Desktop tool within Windows Admin Center. Work-around: deinstalling the remote desktop v4.30.2 and reinstalling the old version v4.26.0 until the problem is resolved in the newer versionWindows Admin Center fail to work after installing June cumulative update
