Administrators can't install from CD

I am the administrator of a Windows Active Directory domain. Recently (a few days ago), we started having a problem where people that have local administrator permissions on PCs were getting error messages when trying to install software saying they did not have permission.

Testing revealed that this was happening to anyone with administrative permissions, including my domain admin account, but the tricky part is that it only happens if you attempt to install from a CD-Rom. If you install from the hard drive, it works fine (including if you copy the contents of a CD to the hard drive and run the setup program from there -- runs without any problem). I do not know what could have recently changed to make this happen.

This is a Windows Domain with primarily Windows 2003 servers, a few Windows 2008 servers. All client PCs are XP Pro.

Have you tried adding the PC's themselves to the Administrators Group?

Almost sounds like a group policy is being applied that restricts installing software from removable media.
If you log into the PC locally using the local administrator account, do you get the same results?

Run GPResult or use the Group Policy Results node of the GPMC to see exactly what policy settings are applying to the affected users and computers.

10 Tips to Protect Your Business from Ransomware

Running as the local admin works fine. I am pretty confident that it is a group policy causing this, I just don't know which one. Is there a policy that prohibits removable media installations but not local installations?

A likely culprit is the Prevent removable media source for any install setting under the node User Configuration\Administrative Templates\Windows Components\Windows Installer.

This list is handy for finding particular policy settings.
