It mite not actually be disconnecting. Sometimes Windows 7 displays it as Disconnected (Red X) but it actually connects if double click the shared drive. I have this problem with SIMS where the S drive shows as disconencted and SIMS 'cant connect to S: drive'. To fix this, I open the S: drive, close it, and viola. To fix this, I wrote this (42514c89ce17c0cc9756c10e04e71036.png) in GPO. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System is what goes off the screen.

Hope this helps,
