500 error from localhost on fresh IIS install under XP

Category: asp.net / Tags: no tag / Add Comment

I’ve been using the development server in VS for my toy ASP.NET sites so far, but decided to play with IIS yesterday.  I popped up in the XP Pro CD (RTM bits, not slipstreamed with SP2) and installed IIS only to hit this problem today when I tried to browse to localhost.

Now that it’s up and going, and since I installed IIS *after* the .NET framework, I’m going to go run aspnet_regiis and get back to actual asp.net work. 

Why even bother with ASP support since I’m not going to use it?  Valid question, but the answer is just that I wanted to get it fixed because it didn’t feel right to me :)

The famous ‘Class not registered’

Description:
The server failed to load application ‘/LM/W3SVC/1/ROOT. The error was ‘Class not registered’.
  1. comand line “msdtc -resetlog”
  2. rundll32 wamreg.dll, CreateIISPackage
  3. regsvr32 asptxn.dll
  4. IISRESET
