I'm currently running DNN 5.1.2 with Windows XP Pro, using SQL Server 2005 and with IIS 5.0. The issue i'm running into is that whenever I fill in a field on my DNN site, like a dropdownlist or text field, as soon as I click a button to submit the data the page just refreshes with all the information gone. And when I say all the information gone, I mean the dropdownlists no longer have items and the text fields are all empty. I've had another partner working on this project too and on his local machine using the same code, same DNN version, and same SQL Server, he does not run into this issue. I have also logged into his machine from my computer and the site works fine. So I've ruled out that this problem is a browser or code issue. Also this code does work on our production server. So it’s just my local machine that this is happening on. My only idea is that this is some configuration issue. Also we've compared web.config files and they match. Does anyone have any ideas? we've been working on this issue for over a week with little progress on the issue.

I actually have .NET 3.5 and believe Ajax 3.5 comes with that right?
