I still think you'll be better served by an all TCP/IP network, it's just a question of how you want to overcome the ubiquitous nature of B-node implementations. Our NetBIOS over TCP/IP includes NetBIOS to DNS name mapping support so you aren't limited to a single broadcast segment. It also allows you to load and unload NetBIOS, TCP, and IP (though if you buy into the idea of one protocol stack that feature isn't all that useful in a LAN Manager environment). Or you could look into using NetBIOS 'bridges' to connect your various segments. I know Performance Technologies provides one and I know there are others out there. Lastly, there are M-node implementations out there -- if I can believe my LAN Manager installation instructions, UB does sell one. enjoy, leo j mclaughlin iii The Wollongong Group ljm@twg.com
