Windows 7 with mapped network drive from windows 2008

We have installed a new network with Windows 7 workstations that are mapped to a Windows 2008 2r file server as a domain.  I have mapped the Windows 2008 server as a network drive on each machine to operate accounting software.  Six of the workstations are working fine and data is being updated to the file server.  One workstation appears to be fine as for as the connection to the database, but the transactions are not being updated to the same database as the other workstation.  It looks as if this workstation to connected to another copy of the database.

I checked to see if I could find another copy on the file server.  There wasn't another copy of the database.  I disconnected the mapped drive and reconected that same network drive.  The application still displays information of an old database.  I checked the mapper drive and I have noticed the the icon for the mapped drive show different than the other workstations.  This icon for the mapped drive shows as 'CSC-CACHE' and not like the other workstation.  Somehow this workstation was setup different.  I think it has something to do with 'Always available offline" .  My quetion is, How do I disable this so I can map the network drive like the other stations?
