Service Unavailable error for IIS application pool

[Guest]

I have successfully used a domain account to serve as the identify for a
"Windows Authentication Only" ASP.Net web application on one Windows 20003
server, but cannot get it to work on another Windows 2003 server. The error
on the second server is "Service Unavailable".

If I switch the custom pool to use the default Network Service authority and
grant that authority access to the web site root folder via ACLs, everything
works. If I switch it to use the custom account, any attempt to access the
web site - even a static HTML page - produces "Service Unavailable". The
custom account is not locked, the password in the custom pool is correct, the
aspnet_regiis /ag command was used to grant access to the metabase and the
ACLs on the web site's root folder was set for read-only rights. The
application uses the custom pool and has rights to read, run scripts and run
executables. W3SVC raises events 1057 (warning), 1059 (error) and 1021
(warning) and the custom pool is stopped.

I have gone through the security policies on both machines using a comparer,
and there are no additional restrictions on the server that the error occurs
on. I restart the pool and web site prior to each test.

I have looked on Google and MSDN KB and Premier support KB and cannot find
anything that fixes the problem.

I am stuck. How can I diagnose this problem?

You may temporarily add the domain account to local administrator group and
then reboot your server, Will this fix the problem? If so, it should be
still a permission issue.
