Their DB server does have the correct time, synchronized with the web server's time. The web server is Windows 2008 R2 x64, and the SQL server is SQL 2008 Web edition. I had them check the time last week. They were a couple minutes off, but have since fixed it.
 
They are in a different time zone than me and my users. I'll report back when I hear about my application pool inquiry.

RadioActiveLamp I've just looked up Winhost and it appears that they set the app pools to only 100MB of memory! You can not run any ASP.NET or Classic ASP application in 100MB of memory. 

Your problem I suspect would be the app pool recycling. If you have anything over 20 active users on your forum it will probably recycle every 10 to 20 minutes causing loads of issues.

To give you an idea we set application pools for our own hosting services to 800MB for each website and 500MB for the free hosting websites:-

Well, that is a problem...
 
At slow times, I have 35 active users, but frequently jump to 60+

You could consider jumping boat and asking Bruce to take over the hosting for you RAL - then problem solved Wink

So basically you are saying that if we  have unlimited RAM App Pools, and we still get SESSION TIMEOUTS it probably is a memory shortage problems ?

There are lots of different things that can cause sessions to be dropped, including when the app pool is set to recycle, if app pool crashes, using multiple worker processes for the app pool, load balanced servers that are not session aware, other applications forcing sessions to be dropped, etc, etc.

However, if your Web Wiz Forums installation is set to store sessions in databases it should reduce the impact of the application pool being recycled, but would still affect the new post indications and the active users list.
