Virus NIMDA on Netware server 4.11(HELP)

I have a 4.11 Netware server that has files infected on one of the mapped drives on the network and am trying to install Netshield 4.5. The instructions state to load “clibaux.nlm on the server prior to installation. I tried to load the NLM but theserver stated it was unable to find it. Does anyone know what I need to to do. Users can access the info on the server but I want to keep them from accessing Word & Excel files until I can scan the server for infected files. Last night I scanned 400 files using Mcafee 4.5 from a workstation. Mcafee advised to install Netshield on the server and then scan files.

thanks,
Rob
