When you use the Windows NT AT command to schedule a process that requires a drive to be mapped to a NetWare volume (through Gateway or Client Service for NetWare), the drives that are mapped by the scheduled process are not accessible to any user or application except those started under the scheduler service. Similarly, the scheduled process cannot access Netware mapped drives that were not established by the scheduler service. If you attempt to map that drive, the following message appears:

If you attempt to delete the connection, an error message appears, stating that the network connection could not be found.

The mapped drive does not show up as a valid drive in File Manager, but in some cases it may show up in the disconnect network drive list from the toolbar. If you try to disconnect that connection from within File Manager, the following error message appears:

The scheduled command or batch file that establishes the connection should also terminate that connection by adding a NET USE <drive> /DELETE command to the end of the file.
