I have Windows 2008 R2 servers as my DCs. I create a group policy on the 2008 servers to map my network drives. In Windows XP it works great 100% of the time. In Windows 7 this is not the case. I can't see the drive letters in My Computer but if I go out to DOS and look using the net use command I can see the drive letters 100 % of the time. I can also see the drive letters within programs. I just can't see them within My Computer. I looked at the Reg setting for the following settings and they are not in play.
I can use My Computer and map to the network drive, click Reconnect at Login and the dirves then will show up for me each time I login. I have about 150+ Windows 7 machines out in the field and I need to deploy about another 300 or so soon but the drive letters not showing up in My computer is holding me back.
