I recently did an in-place restore of an Azure VM from 15 days ago, and while the restore seemed to go smoothly, I'm having trouble with RDP access. When I try to connect using the DNS name, I get the error: "An authentication error has occurred. The specified network password is not correct." If I use the IP address, I see a different error: "The computer that you are trying to connect to requires Network Level Authentication (NLA), but your windows domain controller cannot be contacted to perform NLA." The VM is running, and I can execute PowerShell commands on it, but I suspect there was a computer password change during the restoration process. I've already attempted to disable NLA using the Azure command and rebooting, plus I've reset the computer in Active Directory, but nothing has worked. Any advice on how to resolve this issue?

I faced a similar problem once, and fixing it was quite a hassle. A good first step is to check the health status of the VM agent; if it's reporting errors, that could be the root of your connection troubles.
It sounds like the computer password might have changed during the restore like you mentioned. One option to try is rejoining the machine using the Serial Console or attempting to RDP with a local account. If you aren't familiar with the local account password, you can reset it directly through the Azure portal.
I checked the health status, and there are no complaints on it.
