CSNW Does Not Support MS-DOS Name Space Correctly

• Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0
• Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

SYMPTOMS

When a connection is made to a Novell NetWare Server, Client Services for NetWare (CSNW) checks whether the volume supports OS/2 name space. If it does, CSNW enables long file name support on that connection. However CSNW only provides long file names for that connection . An application that needs MS-DOS name space will fail.

CAUSE

CSNW does not support MS-DOS name space if long file name support is enabled on a connection.
