Novell Netware

[Sudeep]

Hey guys Can someone please help me out. Whenever i Go to Control Panel
"Users" and try to change the "Way users log on options" I get a message
which says-"Client Novell Netware is enabled & in order to edit these
settings or to enable fast user switching please disable or delete Client
Netware"
I have no clue as to how to uninstall the above mentioned service. I have
even tried disabling the service under the services section of
"Administrative tools" but to no avail.
