After swapping an OS disk back to a snapshot, cannot RDP to server

Question

I tested reverting to a snapshot disk by swapping the OS disk of a VM. Now when I try to RDP it says "network level authentication is enabled, but the domain controller cannot be contacted." The VM is on the same subnet as the domain controller (also a VM in Azure). Why did this happen and how do I fix it?

Answer 1

Sounds like the trust relationship might be broken between the VM and the DC. You can either try to utilize Run Command in the left hand pane, by running the DisableNLA command or you can try to run the following powershell command to fix the trust relationship.

Test-ComputerSecureChannel –Server <DC IP> -Repair -Verbose -Credential (Get-Credential)
