This article was previously published under Q152987 SYMPTOMS
When you run an MS-DOS application that accesses data on a NetWare server
through Client Services for NetWare (CSNW), you get an error mesage
reporting a sharing violation. If you run the same application on a client
running Novell's VLMs, it works correctly. It will also work correctly from
Windows NT if the data being accessed is moved to a Windows NT server.
CAUSE
When an MS-DOS application attempts to open a file using an MS-DOS
compatibility open, CSNW will look to see if the open is for READ or not.
If the open is for READ, CSNW sets the sharing on the file to SHARE DENY
WRITE. If the file is being opened for anything other than READ (for
example, WRITE), CSNW will set the sharing on the file to EXCLUSIVE ACCESS.
Therefore, CSNW will only support a file being opened more than once
through an MS-DOS compatibility open if all instances of the open are for
read-only.
RESOLUTION
This is by design.
STATUS
