C#, .Net 3.5 and Ajax

Question

.NET3.5

We have an internal web application that uses C#, .Net 3.5, and Ajax/Ajax Toolkit from Microsoft. When we have EnablePartialRendering set to true, we get an error Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object in ScriptResource.axd. I've tried turning EnablePartialRendering to false based on some advice I found online, but this causes issues with our UpdatePanels we have on the site.

The clients are running IE Ver 7, and the server is IIS Server 7 running on Windows Server 2003.

Any help/advice you can provide will be appreciated.

I'll give this a try. I won't be able to push this to production until late tonight, but I should have a response pretty early tomorrow morning if it works. Once I have positive confirmation from my users, I'll be sure to "Accept Answer" and rate your response a 5!

Ok, this did not work, my users are still getting the Sys.WebForms.PageRequestManagerServerErrorException when using the site. I've replaced all of the <asp:scriptmanager... xmlns:asp="#unknown"> with <ajaxtoolkit:toolkitscriptmanager... xmlns:ajaxtoolkit="#unknown">. Any other ideas of what I can try?
