Group Policy folder redirection reversal…

I have a client who has had three different people handle the IT in the past. It is a MESS. Now they have contracted with the company I work for to administer their network, I’m the lucky sap who gets to straighten things out. They have a 2003 Server Small Biz system running XP Pro clients. The folder redirection was done through group policy and I want to reverse the Application Data redirection as it is causing users with Firefox to have some really screwy problems. Removing the policy does nothing, even after doing a “gpupdate /force”. How can I redirect this folder?
