Browsing the network

I seem to having trouble viewing all machines on the network when browsing Network Neighborhood. I have two domains, one with NT4 servers and the other with W2K servers. The NT4 domain can browse all of the W2K domain. However, if I logon to the W2K domain and try to browse, I can not see the workstations or servers in the NT4 domain.

I setup DNS, Wins, and Lmhost files in both domains. Nothing works. Any suggestions?
