Folder Redirection Error

We have a W2kAS with AD running. We have user drives on the server (\\Server\Users\%username%). We have W2kp and XPp clients and am trying to use GP to redirect local My Docments to user drive. I am getting the following error that I don't understand.
"Failed to perform redirection of folder ....while copying \my doscuments\desktop.ini ... the security descriptor structure is invalid." This logs event id 112.

Thanks for the help
Jeff
