Slow Performance Saving Documents to FPNW Server (187766)
The information in this article applies to:
- Microsoft Windows NT Server 4.0
This article was previously published under Q187766
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).
