Drive Mappings Not Processed During NDS Login Script Execution

ID: Q186804

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0

SYMPTOMS

When logging on to a NetWare NDS Tree from Windows NT, NetWare login script execution may fail intermittently, resulting in drive mappings not being processed.

CAUSE

When a Windows NT client logs on to NDS, the NetWare server that processes the users login script requires a licensed connection. If this server is out of licenses, a connection cannot be established and the login script fails to run.

MORE INFORMATION

The following is a sample frame for trace comparison.

With an NDS login that works correctly, an NCP command "Change Connection Authority State" is processed, followed by an NCP command "Open Stream."

In this example, a failure response is returned for the NCP command "Change Connection Authority State." The failure code is E0.
