Applications Testing for Directory Existence Fail (159447)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q159447 SYMPTOMS
An application does a test to see if a directory exists on the Windows NT
4.0 file server, and an MS-DOS error 3 "Path Not Found" is returned. This
same application worked fine in Windows NT 3.51.
CAUSE
This error only occurs when the server evaluates the server message block
(SMB) command 81 (Search Directory) sent across the wire and only when
search attributes of 1016 are used. Because search attributes can only
occupy the first 8 bits of the word, the bits beyond 8 were previously
ignored. But in Windows NT 4.0, these bits were not ignored, causing the
server to return an error to the client.
RESOLUTION
The code has been changed to now ignore bits that are not relevant. Install
the updated file.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0.This
problem was corrected in the latest Windows NT 4.0 U.S. Service Pack. For
