[Blind-sysadmins] Inoperative stored user names and passwords

Hi everyone, we have one remote user that users her XP Home laptop to connect remotely. She can no longer save passwords in stored user names and passwords. In log on credentials dialogs the save password check box is missing. When I go into control keymgr.dll there is no "add" button and the only button that is not grayed out is the close button? This started after doing Windows updates. Has anyone ever seen a stored user names and passwords dialog that is inoperative? Any suggestions? Thanks Frank
