To fix the Windows Login error “The specified Domain either does not exist or could not be contacted.”
Do the below
Open Regedit
regedit
Locate the reg directory
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server
Then add a new dword entry called “IgnoreRegUserConfigErrors“.
Once added change to decimal and add the value as 1.
Then re-attempt login and this should work.
