windows 2000 and netware passwords

I have taken on a new position which requires me to upgrade a number of win98 boxes to win2k. The problem or at least frustration is when users login to the netware 4.1 server and after successfull authentication they are required to supply user name and password credentials for win2k as well. I have created all the users accounts required on each of the local win2k boxes and all works fine. My question is this: Is there a quick and easy way to get around having to input usernames and passwords twice. I know the obvious, get rid of novell right, not an option right now. If I leave the win2k password credentials blank in the new user manager the users are still asked for a username to get into win2k. I do not have and do not want to add zenworks or other management suites to novell. Any suggestions would be appreciated.
