OK, I found a solution... finally !
I modified the file sys:\bkupexec\advrtms.dat on the Netware server to use the IP address of the BE Windows Server and not the name. Then I ran BESTOP.NCF and BESTART.NCF on the netware server.
At this point, I am able to see and select the Netware server for backup jobs.
One other quark, the 'Test Volume Credentials' screen that allows you to test and make sure the login account name and password are working does not work when you select a Netware server. I receive 'access denied' each time I run the test. I have tried every possible combination of user name, NDS context, full distinguished, etc. and none of them work. But, if I skip that step, the back job runs just fine without any 'access denied' errors.
