Failed to access IIS metabase ERROR

Got to be one of the most fustrating errors to get after you have spent over a week developing a ASP.NET (2.0) web applications.  So I searched the greatness that is the internet and found many a fix...  sorry, little sarcasm there...

Turns out, installing IIS on an XP sp3 Pro computer AFTER you have been developing is a BAD THING!  I read and read and figured after 5 sites, maybe I need to basically start over.  THANK YOU Amit S Patriwala!  His blog post was the answer to my issue.  I will recap...

If you get this error, follow the steps below:

1. Stop panicing
2. Run the following in a CMD window:   C:\windows\microsoft.net\framework\v2.0.50727\aspnet_regiis.exe -ua  This uninstalla ALL ASP.NET framework.
3. Run C:\windows\microsoft.net\framework\v2.0.50727\aspnet_regiis.exe –ga ASPNET next.  This tells you what the rights are for the ASPNET user.
4. Next, run C:\windows\microsoft.net\framework\v2.0.50727\aspnet_regiis.exe -iru This is what fixed my issue!
5. Run C:\windows\microsoft.net\framework\v2.0.50727\aspnet_regiis.exe –ga ASPNET to verify

Those 5 steps solved a two day issue of my site not working on the XP computer running IIS 5.1. 
Hope this helps someone else!
