In an attempt to improve the security of my Windows Server 2008 R2 with Exchange 2010 SP3, I decided to test if File and Printer Sharing was really important to allow Exchange to work (thats all I really need from this server).
When I did, I ruined the server. Reenabling it don't seem to undo the mess.
After a reboot, Windows Explorer refuses to initialize. I'm limited to commands, some parts of Control Panel hang when I try to access them. I rebooted the server again, and now it doesn't even go past "Applying computer settings..."
I have no idea what to do, Google doesn't seem to help. Is it possible that I'm the only animal who ever tried to disable File and Printer Sharing in a domain controller?
How can I recover from this situation?
Note: I can access the shared folders from other network computers.
