In the following configuration, after you log on and log off severalconsecutive times, the network client receives an access denied errormessage to one or more network drives located on the NetWare server. Also,the NET USE command fails with the following error message:
Error 85, Local device already in use
This error message is followed by an access denied error message.
The problem can be cleared on the Windows NT Workstation client byrestarting Client Services for NetWare (CSNW).
Windows NT primary domain controller (PDC) running Windows NT Server 4.0 with Gateway Services for NetWare (GSNW)
Novell NetWare 3.12 server
Client running Windows NT Workstation 4.0 with Client Services for NetWare CSNW and:
Logon script located on the PDC
Desktop icons stored on the NetWare server (M: drive below)
The Windows NT logon script maps several network drives on the NetWareserver. For example:
net use M: /delete > NUL followed by, net use M: \\NWserver\share > NUL
NOTE: The same behavior is obtained using a NET USE command with the/persistent:no switch.
The problem affects one or more drives and the drive where the desktopicons are located is always affected. The problem is intermittent and iseasier to reproduce when using higher speed processors (200 MHz and more).
The solution consists of removing a race condition that potentially exists,especially when using high speed processors, between process cleanup andWINLOGON deleting network connections. To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition.
