NT logon to Novell 4.11

I would like to know if I need to add anything as far as services go on a Novell 4.11 system so I can logon with a NT workstation. I am on a token ring environment. I have all the pre-requesites loaded on the NT workstation and can ping the workstation but I can’t see the network drives and can’t logon to the Novell network to use the resources. Any help would be appreciated.
