We are mapping a windows share with the @NET USE command from the login script: Command Follows:

@C:\Windows\System32\CMD.EXE /C start /B NET.EXE USE Q: \\bdo.com\CIM\DATA\NatlGroups

It works great but... a problem creeps up when the user(s) log off their machine and bring the workstation back up without being connected to the corporate network. The Q: drive is still being mapped. We are not using the persistant command so I am still trying to figure out why this is still being mapped.
