Two things to try:
1. Right-click on the My Computer icon on the Windows
desktop, left-click on Disconnect Network Drive, and disconnect
any mapped drives that are not currently available.
2. See http://support.microsoft.com/kb/918165 "Problems in
Windows Explorer or the Windows shell after you install security
update MS06-015".
