Question : Which protocol to choose, TCPIP or Netbeui

I run a network with 5 NT Servers and about 100 Win95 and WinNT Workstation PC's as clients.
Is TCP/IP faster than Netbeui with this type of network.
I know Netbeui is fast but when the network becomes to large i heard it becomes slower due to the many Netbeui names broadcasts that saturate the network's bandwith.
Would i be wise to stop using netbeui all together and start using TCP/IP. In terms of performance i mean.
At the moment we use Netbeui to connect all NT and Win95 machines. We use TCP/IP to connect to a Lotus Notes server and a UNIX machine.
All machines therefore have both protocols installed.
I think dropping Netbeui would be the best choise because we don't need it to connect en browse on the network and two active protocols use more bandwith than just one.

Answer : Which protocol to choose, TCPIP or Netbeui

It is hard to say which protocol is good or not, it depends on what kind of network you have and what purpose the network serves for.

As you mentioned, you have 100 computers on the network and you know that NetBEUI protocol is not suitable for a larger network. So, if your network would not grow up again, you do not need to change the current status, else you should change the protocol to TCP/IP or IPX/SPX, since they are routable and can be controlled to reduce network broadcasting. When the network become bigger, you may segment your network into two or more separate VLAN or subnet, re-arrange your IP address assignment, route the necessary packages between segments, and more and more.

Also, as you mentioned, you have UNIX environment, if you want all the clients to access UNIX resource or to the Internet, you just only configure TCP/IP protocol, else within your internal network environment, IPX/SPX is also a good choice, since it is faster.

Hope this helps.
