What are the potential consequences of removing local admin access via group policy (2003 domain)?

Currently, all users on our domain have local admin rights.  This is not a group policy; accounts are just added to the local admin group during individual setup.  We would like to remove these previously added admin privileges, but I wanted to check with you guys before I just stepped through a tutorial and enforced the policy.  What are some potential issues that I may be facing?  I do have an alternative method for distributing software updates, but I was wondering if this local admin restriction would effect domain admin accounts as well. If I log onto a PC with a domain account, will the policy remove that account from the local admin group or will the domain admin status supersede the policy?  Thanks for reading.

You may break software that uses admin permissions. For example, you may have an application that writes to C:\IMDUMBAPP\. A standard user can't write to this location. You can use Group Policy File Security to give users the write permission to this folder.

Domain admins and the local administrator account should be left as administrative users on the computer. Here is a guide that will help you: http://deployhappiness.com/managing-restricted-groups-with-group-policy/
