i also have this problem where i got the message "Client Services for NetWare has disabled the Welcome screen and Fast User Switching. To restore these features, you must uninstall Client Services for NetWare." and none of the check boxes for turning on the welcome screen or fast user switching were able to be checked, i uninstalled the network client "Client Service for NetWare" and went back to the logon setting and was able to check off both the welcome screen and fast user switching but when i hit apply nothing happens and when i clicked back into the logon settings neither of them were checked off again?
