My welcome screen will not allow “fast user switching.”  When I try to configure “fast user switching” it gives an error message of “Client Services for Netware has disabled the Welcome screen & Fast User switching.  To restore these features you must uninstall Client Services for Netware.”

However, when I uninstall "Client Services for Netware" (from Network Connections/Local Area Connection/Properties) my internet no longer works.  I don't even know what "Client Services for Netware" is.  How can I get my “fast user switching” to work without interrupting my internet connection?
