IIS "The Local Security Authority cannot be contacted"

This one was a strange one. Our WSS server crashed and rebooted. When it came back up again, users could not login to WSS or IIS and got the error above.

Turns out that due to security configuration we have CrashOnAuditFail set to 1 in the registry and when the server ran out of space, it could not log to the Security event log which caused the CrashOnAuditFail to be set to 2. This caused the server to refuse all, but Administrators to login.

To fix, free up disk space, reset CrashOnAuditFail = 1 and reboot server.
