HTTP 500 - Internal server error

This is no fun message ! When you get this message, a simple restart of W3 services might fix your issues. When you are dealing with ASP.net, some time you end up installing asp.net on your server again ( aspnet_regiis -i from your current framework version sub directory ), in my case, it showed up for no "apparent" reason ( server: Win 2k, .NET 1.1 ). Server Event log showed this message,
Source: DCOM
Error: DCOM got error "Logon Failure: unknown username or bad password" Unable to logon .\IWAM_SERVERNAME in order to run the server.


Source: W3SVC
Error: "The server failed to load application '/LM/W3SVC/1/Root/op.' The error was 'The server process could not be started because the configured identity is incorrect. Check the username and password.

I did some basic test pages ( both aspx and asp ) and found out that both the pages were not serving from the server. (html pages were ok).

After some research (read Googling:) this is what I found out,
"Configured Identity Is Incorrect for IWAM Account!!"
and what you need to resolve this issue is to sync up IUSR and IWAM accounts in IIS metabase. I followed the steps in this MS KB article and the issue was resolved.
