Main file share (Z is accessed via DFS and home directory is not. XP systems appear unaffected. Background:Windows Server 2003 (SP1) domain environment with other 2003 servers, XP Professional and Vista workstations.Group policy deployed and now managed by a Vista workstation. DFS is principally used for acess to the main fileshare and is domain routed. Any suggestions?
