======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

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 about how to do this, view the "Restoring
the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key"
Help topic in Regedt32.exe.

SYMPTOMS
========

Saving documents may take a very long time when the destination is a File and
Print Services for NetWare (FPNW) volume. Although this behavior may occur in
other applications, it can easily be seen using Microsoft Word 6.0.

CAUSE
=====

When File and Print Services for NetWare encounters a sharing violation, it will
retry the file operation on the file multiple times, with a short delay between
each retry, before returning an error to the application. The total delay per
file operation before a sharing violation error is returned to a client is 3
seconds. This is because of a server optimization used by both the Server
service and the FPNW service in Windows NT Server.

A lengthy delay is seen in Microsoft Word because of the fact that Word will also
retry the file operation up to 12 times when encountering a sharing violation
while saving a file. This causes up to a 36 second delay when saving a file with
Word to an FPNW server.

RESOLUTION
==========

Sometimes, it may be preferable to disable this optimization. To do this, it is
necessary to make the following registry modification.

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" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it. If
you are running Windows NT, you should also update your Emergency Repair Disk
(ERD).

1. Start Registry Editor (Regedt32.exe).

2. Go to the following key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
   \FPNW\Parameters

   NOTE: The above registry key is one path; it has been wrapped for readability.

3. Add the following:
   Value Name: LockRetryCount
   Data Type:  REG_DWORD
   Data:       0 (Default: 5)

4. Stop and restart the FPNW service.
