Question : Global group grants access for file permissions but domain local group does not

I'm setting up the permissions for access to shared drives on the servers in our system. (Should have been done years ago but then again, everything I've been doing since I started working here a few months ago should have been).  I'm reasonably new to active directory and domain management and stuff, so this might be a simple solution.

Anyway, I'm trying to do everything right, so I have global groups that are part of domain local groups and the domain local groups are given permissions.  The problem I'm having is the permissions on a different server (same domain).  When I give permissions to a domain local group, only the people in that group that are also domain admins actually get permissions.  But if I add the global group that is a member of the domain local group directly to the folders permissions, then all users get access.  I'm not really sure where to go from here.

Thanks for the help.

P.S. Both servers in question are Windows 2003 R2

Answer : Global group grants access for file permissions but domain local group does not

You can use Computer Management | Local Users and Groups | Groups
This snap-in is not available on domain controllers, just domain members and workgroup servers.

The commandline to add a new local group is: NET LOCALGROUP "Groupname" /ADD /COMMENT:"Description"

The commandline to add domain global groups to that group is: NET LOCALGROUP "Groupname" "DOMAIN\Groupname" /ADD
