CF Forms Hang Randomly - CF 9 Win 2008 R2 MS SQL 2008

We recently launched a new web server upgrading from Win 2000, MS SQL 2000, and CF 8 to Windows 2008 R2, Coldfusion 9 Standard, and MS SQL 2008. Since the launch about 30% of the time my forms hang when submitted. Not just one form, but any form on my site.Different browsers, different operating systems, different networks, different form data. Sometimes they work -- sometimes they just hang for a minute or two and then the broswer throws the Firefox"Connection Reset" or MSIE "Diagnose Connection Problems" error pages.

Nothing on the server logs an error or even an attempt to reach the action page so I can't use cfdump or cflog or anything in the action page. I have had a ticket open wiht Adobe for 4 weeks. My network guys say it isn't the network. The problem usually occurs during business hours at the office and occasionally I can get a form to fail from home. My server guys say it isn't the server (Windows, IIS, or SQL) and Adobe doesn't think it is my code becasue the form works fin 60% of the time.

I am at my wits end. Since it is only on action pages I wonder if it is a POST data issue. All my other ColdFusion database calls and code work fine. Only the action pages of my forms are affected.I am wondering if I might have an Application Pool issue with IIS, but I dont know.

Anyone have any suggestions?

Thanks,
