ASP.NET - The state server has closed an expired TCP/IP connection

[dm3281]

Hello --

I'm getting the messages in my state server's event log (web farm) as
displayed on this blog
http://myblog4fun.com/dmohorn/archive/2006/09/28/26.aspx.

I'm being told that other related business units receive these same error
messages and they're telling me its related to Windows 2003 and SP1. They
said if I rollback SP1, these messages will go away. Can anyone confirm or
deny this?

I have tried changing the session timeout limits from 10 secs to 20 and 30
seconds, respectively, and the messages still display.

Opinions?
