Anyone got any clues what could possibly be causing this error.
Environment is Server 2012 and Windows 8 with roaming user profiles, \Server\Profile$ & \Server\User$.
The trigger that causes this is applying or deleting a printer via GPO. Without doing that the roaming profiles work fine.
Problem is as soon as I add a printer GPO the user profile fails to logon with the error:
Windows cannot copy file \\?\UNC\Server\Profile$\Test.V2\AppData\ to location \\?\C:\Users\Test\AppData\.
This error may be caused by network problems or insufficient security rights.
DETAIL - The process cannot access the file because it is being used by another process.
At which point the user can no-longer connect to either \Server\Profile$ & \Server\User$ but other shares are unaffected.
We then run network monitor and trace the failing packet to:
System x.x.x.5 WIN8 SMB2 SMB2:R - NT Status: System - Error,
Code = (34) STATUS_ACCESS_DENIED IOCTL (0xb) {NbtSS:3, TCP:2, IPv4:1}
No event logs on the server logging any events at this particular time.
Any suggestions?
