Today one of my colleagues decided to try and free up some space by taking the entire users directory from our Windows Server 2008 R2 installation to another drive. This has caused the problem of users not able to logon to the server at all, even when the directory was replaced. Through some trial and error I found that I could once again logon to the server if I renamed the ntuser.dat file. This only allows for one logon and only to a temporary profile. Regedit shows that renaming the ntuser.dat file will create a new registry key for that user with the same extension.
The problem is that this server houses a business critical application and needs to be available to everyone through RDP. Aside from recreating all users, is there any way to get the logon's working again?
We are in a domain and the domain controller is on another server, so we have access to basically everything except the RDP server.
Does anyone know how to fix this?
