HPFS.386 Returns Wrong Error for File Creation (94229)
This article was previously published under Q94229
SUMMARY
Many applications use Int 21 to create unique temporary files.
However, a problem has been discovered with HPFS.386 that can result
in an infinite loop within this process.
PROBLEM ID: PR9301001
SYMPTOMS
If you attempt to create a new file in an HPFS386 directory that is
read-only, the error returned is "file exists." If Int 21 is trying
to create a temporary file and it receives that error, it will
increment the temporary file name by one and repeat the request.
There are two symptoms this creates. First, the client PC will hang
or go into "beeping death." Second, the server will slow down as it
is processing repeated attempts to create the file. Typically the
disk light will stay on, and you will notice performance
degradation with other clients until the offending client PC is
rebooted. This behavior has been observed by users of Microsoft
Word and PowerPoint, but the potential for problems extends to any
application that creates temporary files on LAN Manager 2.1
servers.
CAUSE
This problem is caused by an incorrect return code from HPFS.386.
RESOLUTION
HPFS.386 should return extended error 65 (access denied). It has
been modified to correct this problem. If you are hanging while
attempting to save documents to read-only directories, replace
HPFS.386. Replace <lanroot>\NETPROG\HPFS.386 with a patched version
dated 7/23/92, available from Microsoft PSS (CSD00.050).
