While you posted your request in the Novell Netware section, I assume, you are dealing with a client computer, that connects to a Novell Netware server. So if there is a Novell Netware Client installed on that computer, there should be an option named "Workstation only", which you have to tick on, to login to Windows system only.
But after that, you might be asked for the Windows password, which is needed, to login to get the windows desktop.
