Hello all.  I've spent the past 5 hours Googling and hanging out with some ASP/IIS guys to try to resolve this before bothering the folks here.  I'm not too experienced in .NET, so the mess I've gotten myself into should prove pretty funny.  Hopefully, it'll be funny because the solution is just a few hours away, instead of a complete redo.  :o

Sitting on the wrong box, I make the mistake of running aspnet_regiis.exe -ua.  Done.  Gone.

Of course, immediately after this the webpage in question stopped working.  I've since repaired .NET 2.0.50727 and reinstalled ASP.net.  No avail.  I continually get the following error in my Application Long:

I receive the runtime error on the server immediately after AD has confirmed the account.

I'm sure.  I'm hoping.  I'm sure hoping that I'm just missing a simple reregistration somewhere, or that someone can point me in the right direction.  If anyone has any suggestions, please let me know.  I very much look forward to hearing from you.

Thanks in advance.
