To me this looks like the debugger is trying to attach to the process. This can be caused if you have both framework 1.1 and 2.0 on your machine and an IIS virtual folder configured for framework 2.0, but you are trying to debug with VS 2003. Or some such mismatch of CLR's and debugger.

In IIS right click the virtual folder for your project and select properties. Click the ASP.NET tab, In the ASP.NET Version drop down select 1.1.4322, click the apply button and click OK. That's it.
