SERVER APPLICATION ERROR

Hi im an ASP.NET novice..but i am having an issue. Every time I run my web application i get this error, and it tells me to check the event log. When I do, I get the following message from 'W3SVC':

The server failed to load application '/LM/W3SVC/1/Root/XXXX'. The error was 'Class not registered
'.
For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp.

For more information, see Help and Support Center at

The other peculiar thing is that my no longer existing favicon is still there when I try to open the web app

I am very confused and appreciate all teh help I can get.

Hi,

this is a known issue. follow the suggestion below:

This problem is related to Component Services, and when you open Component Services MMC, you will most probably get Error Code 8004E00F COM + was unable to talk to Microsoft Distributed Transaction Coordinator. So, fix the COM+ services first by using the following KB.
PRB: Cannot Expand "My Computer" in Component Services MMC Snap-In
http://support.microsoft.com/?id=301919

If the above didn't solve it, and you still receive the 'Class not registered' error message, then you need to recreate the IIS packages in COM+, try

a) Delete IIS related package in Component Services MMC
? IIS In-Process Applications
? IIS Out-of-Process Pooled Applications
? IIS Utilities

b) Open command prompt, navigate to %windir%\system32\inetsrv folder, and enter (case sensitive)
c:\winnt\system32\inetsrv\>rundll32 wamreg.dll, CreateIISPackage
then
c:\winnt\system32\inetsrv\>regsvr32 asptxn.dll

c) EnterIISRESET at command prompt to restart IIS services, then re-open Component Services MMC to verfiy the IIS packages are recreated.
