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

 - Microsoft SNA Server, versions 2.11, 3.0 SP1, 3.0 SP2, 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
========

When the SNA client attempts to get its sponsor connection from a specific SNA
Server computer and it receives an error, the SNA client never tries to connect
to another sponsor server listed in its sponsor server list. Instead, the SNA
client repeatedly tries to connect to the first SNA Server computer that it
attempted to connect to.

WORKAROUND
==========

For SNA Server clients using Windows NT or Windows 95, a registry entry must be
added in order for users to specify a SponsorRetryDelay time in case
TerminateIfNoSponsors is disabled. This registry entry gives slow wide area
networks or SNA Server computers time to recover from failure.

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.

To work around the problem, add the following registry entry:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SnaBase\Parameters:
   SponsorRetryDelay:REG_DWORD:<retry delay in seconds>

NOTE: The default retry delay is 15 seconds.

STATUS
======

SP1, 3.0 SP2, and 4.0.
