Ok, now I am writing this after panicking for about an hour after updating my server from .NET 2.0 beta 2 to .NET 2.0 RTM. After uninstalling beta 2 and then installing the rtm for .net 2.0 I noticed that my .net 1.1 sites no longer worked. Two things happened. On one of the 1.1 sites it changed all of the page mappings to 2.0. That was an easy fix, I just changed the mappings back to 1.1.

The second problem was stranger. I could not find any aspx pages on the site. Although I had proper mappings reset. The problem again was in the web service extensions. Believe it or not I went on that track after searching for "404 error only on aspx pages asp.net 2.0" and finding an old post of my own. Go figure. Anyway I went to IIS and clicked on Web Service Extensions. I noticed that the ASP.NET v1.1.4322 extension was not even there anymore and that it had gotten deleted. All you need to do is click the "Add a new web serice extension" link and then name it "ASP.NET v1.1.4322" and then browse to "C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll" when it asks after you type in the name. Do not forget to click the "Set extension status to Allowed". Everything should work fine now.
