Disabling local admin account prevents a Domain Admin access

I am running serveral Windows 2003 Servers, and I am having a very odd problem.

One one server (not a domain controller), I have the following default accounts:

Local Account: Administrator

Local Group: Administrators: Members: domain\Domain Admins, Administrator (local)

Domain Group: Domain Admins: domain/Administrator, domain/Turner, domain/Green

The problem is this. When I disable the local administrator account on the file server, domain/Green is denied access. All my other users, as well as domain/Turner and domain/Administrator still have complete access. If I reenable the local administrator account, access for domain/Green comes back.

This is a very odd problem does anyone now of a utility to check the integrity of local security accounts, or have any idea what this could be?

Change the local policy to default.
Then add the accounts you need to local admins group again.

Go to START - RUN - type MMC - Add snap in - security configuration and analisys - then save a data base choose one template and appply it to the machine.
