Unable to change file associations

I have a relatively new domain with one Server 2003 domain controller, and many Windows XP Pro SP2 clients. Members of the "Domain Users" group are unable to change file associations via Folder Options --> File Types in Windows Explorer. When they navigate to that location, all buttons are grayed out.

I've checked HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer

as well as

HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer

for the NoFileAssociate dword value. Numerous search results indicate this value controls access to the "File Types" dialog. However, I can't find this value anywhere within the registry on the systems of my domain users. Attempts to create the value and give it the appropriate data still fail to yield results.

I'm a little stumped so far. Any thoughts or ideas?
