After following all of the other suggestions:

1. Check "Log on as a service" and "Log on as a batch job" permissions
2. Check folder permissions, c:\Windows\system32\inetsrv, etc.
3. In Metabase Explorer check permissions for IIS_WPG group

Remember to restart the IIS admin service!

After trying all of the above and nothing worked, I noticed the event data in the event log error was 80070700. googling for this error yielded "An attempt was made to logon, but the network logon service was not started."
