Multiple Users on W2K PC & Novell logon

We currently have many win2k machines (sp3) that log into NDS and ADS. On multiple user machines we would like to have the users log into the machine locally (rather than ADS) and still use the novell client for windows 2000. Plus this must be secure so only authenticating to NDS allows access to the machine while suppressing the windows logon (with local adminstrator authority). I can suppress the windows logon with a registry hack or tweakUI but this unsecures the desktop. I'd like a secure logon to the desktop that doesn't require me to create 20 profiles for each machine and its users. And still run the novell client for NDS. We will be implementing ZEN in the near future. What are my options (if any)?
