Unable to Build Switchless Storage using Network ATC
I would like to point out that I did also try some troubleshooting with AI and it thinks the following summary is the problem. Figured I would post this as well in case this is useful information to anyone online here. I tried to include it in my original post but I think this is what was causing my post to get blocked as SPAM.
The Windows Server 2025 NetworkATC PowerShell module calls Get-HUDSwitchlessMapping before submitting a switchless storage intent. Get-HUDSwitchlessMapping attempts to read HKLM:\Cluster\NetworkHUD\Mapping\<ClusterName>, but that registry path is never created on a healthy three-node Failover Cluster. As a result, ConvertFrom-Json receives $null, the wrapper catches the exception, and Add-NetIntent -Switchless always throws Failed to fetch physical NIC mapping from the Network HUD service.
