It took me a while to figure out how to enable debugging on a traditional .asp project with Visual Studio .NET using Windows 2000. I would always get an error saying:

“Unable to find project on the Web server. Unable to set Web server into correct debugging state automatically. You may not be able to debug .ASP pages.”

After a lot of online research and fiddling with the settings, what follows is what worked for me.

To enable .asp debugging change the following settings:

• In VS.NET:

  -------------   project - properties      configuration properties         debugging            - enable ASP debugging            - enable ASP.NET debugging

• In the IIS snap-in:

  ----------------------   default Website - properties      home directory tab         configuration            app debugging               - enable ASP server-side script debugging   Website (the project you want to debug) - properties      directory tab         application name: add

  This sets an application name for the Website and changes the icon from a default folder icon to a Website icon.

• Add IIS process account to Debugger Users group:

  ---------------------------------------------------   In Computer Management snap-in:      System Tools         Local Users and Groups            Groups               Debugger Users - properties                  Add user IWAM_machine-name (the "Launch IIS process account")

• Now, to debug in VS.NET:

  ------------------------   right-click the .asp page that the application should start from      select "Set as Start Page" 
     set a breakpoint in the .asp code anywhere in the project   click Debug?>Start or press F5 to build the project and start debugging

I hope this helps others to avoid wasting time fiddling with all these settings!
