Windows 2000 Domains and NetBeui

My question is, we will have 9 windows 2000 servers in our new domain and a mix of 2000 pro, 98 and 95 clients. We are looking to go pure IP with DNS. Is this possible. I have read that native mode is that all the servers have to be 2000, not neccesarily the clients. But we are having some browsing issues. We are looking into adding NetBeui as we had to in our NT4 network to get the browsing right. Anyone have any idea’s? We are trying to stay away from win’s and just try and use TCP/IP and DNS to do our resolving. Any Info Would Be Great! Thanks!
