We’ve had a rough few days with some virtualized servers on our testing infrastructure. Some SAN issues required some repair installs on a couple VMs, then we had a couple corrupted partitions on those VMs.
I’d fixed all those issues up, but ran in to problems trying to RDP directly in to the systems. I’d get errors “the Group Policy Client Service failed the logon” after entering my credentials.
Turns out the user profile on the server was corrupted. I didn’t have much in there, so I simply deleted it (System, Advanced Properties, User Profiles). This deleted the corrupted profile and I was able to get on the system successfully.
