IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information on how to do this, view the "Restoring
the Registry" online Help topic in Regedit.exe or the "Restoring a Registry
Key" online Help topic in Regedt32.exe.
SYMPTOMS
After applying Service Pack 5 for Windows NT 3.51, any Microsoft Mail
postoffices that are shared using File and Print Services for NetWare
(FPNW) may experience errors. External.exe may log an error [012] when
delivering mail to the postoffice. Dirsync.exe may not run automatically,
and may generate a warning [154]. When you perform a manual DirSync, the
postoffice will receive updates but will not send any updates to other
postoffices.
CAUSE
A problem was introduced while attempting to improve an OS/2 file-date
issue.
WORKAROUND
Two workarounds are available.
Method One
One is to edit the registry to disable the file caching for FPNW. This
should have only a minor effect on performance.
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys And
Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and
Delete Information in the Registry" and "Edit Registry Data" online Help
topics in Regedt32.exe. Note that you should back up the registry before
you edit it.
- Run Regedt32.exe.
- Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FPNW\Parameters - Choose EDIT and select ADD VALUE.
- Type the name of the value as:
- Set the type to REG_DWORD and enter 0 (zero) for the value.
Method Two
The second possible alternative is to replace two files from Service Pack 5
with two files from Service Pack 4 or the original File and Print Services
for NetWare disks.
- Locate the following two files on the affected server:
Fpnwsrv.sys (System32\Drivers)
Fpnw.dll (System32) - Rename the files to something like Fpnwsrv.sp5 and Fpnw.sp5.
- Copy the same files from Service Pack 4 or the FPNW disks to the
appropriate directories.
- Restart the server.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51.
We are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
