Unable to Connect to Down-Level SMB Server

ID: Q239447

The information in this article applies to:

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

SYMPTOMS

A Window NT-based computer may not be able to connect to a down-level Server Message Block (SMB) server, such as an OS/2 Warp server, if the file system name on a share's down-level server is eight characters or longer. For example:

E:\>net use * \\Server\Sharename
System error 234 has occurred.
More data is available.

The problem occurs the first time you try to connect to the server or you reconnect to the share after it was automatically disconnected. Typically, you can connect or reconnect to the share after two or three attempts.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.

   08/09/99  12:51p             265,008  Rdr.sys       Intel

WORKAROUND

To work around this behavior, contact the manufacturer to have the file system name changed to less than eight characters.
