ASP.Net error: The Local Security Authority cannot be contacted

Question

I had a working asp.net site under development on IIS6 and Server 2003, and then something changed. I reset IIS and now I am getting the error message

The Local Security Authority cannot be contacted

The IIS logs show the return code as 500 0 2148074244

I have no idea what happened, but there is nothing in any of the logs indicating why. Does anybody have any ideas?

Answer 1

The problem was with the app pool identity. Somehow the service account name lost its domain.

The app pool was running as app_svc when it should have been running as domain\app_svc.

When the domain\ was added back to the service account name, everything started working again.
