DFS Issues from WIndows 2003 Server SP2

I’m trying to access a folder that’s presented by DFS and resides on a NetApps filer. I can connect to it from a Windows XP SP2 workstation without issue, however from a Windows 2003 Server I get the message “Access Denied”. I’m definately using the same domain credentials so I’m a little confused.

I was wondering if anyone else had this odd setup and had encountered something similar?
