NASI redirector won’t work w/ Win 2KPro

Hi, we just got a brand new test workstation, It has Windows 2000 Professional installed as the OS. We have a Netware 4.11 server. The problem is when I go to install the NASI redirector to create the modem ports, I get a error message, win95.dll not found. Installation aborts and I can’t set up my modems. I went to Novell’s website and downloaded Client32 4.8. Couldn’t find anything about the Redirector. Need help, please!!
