Substituting NetBEUI protocol for TCP/IP

[CMAR]

I have a 3-computer LAN with broadband internet connection. Computers 1, and
2 are WIN 98-SE systems, and Computer 3 is a WIN XP Pro system.
For security reasons, I replaced the TCP/IP layer for windows networking
with NetBEUI, i.e., I removed the TCP/IP bindings to "Client for Microsoft
Networks" and "File & Printer Sharing" after the same bindings were added to
NetBEUI.
I did that on the two WIN98-SE machines, which now can communicate with
each other but not with the WIN XP Pro system.

Do I do exactly the same thing on the WIN XP Pro System?

Thanks in advance, CMA

Well, sure, I suppose you could visit Microsoft and download the netbeui
support that the retail XP Pro CD is missing.

Why you're doing all this is the real question...especially in the name of
"security"...

In the old days, this technique was called 'protocol isolation'. It can be
effective but you always have to have a 'gateway' system that has one or
more protocol(s) installed and provides protocol-translation between the
two. Unfortunately, there is no way to translate a NetBEUI packet into a
TCP/IP packet. That being said, if you're trying to secure your systems from
access via the public Internet, there are more effective methods, in my
opinion. Expand on your security goals and someone can offer a more 'clean'
solution. Lastly, IP is a layer 3 protocol, NetBEUI is a layer 2 protocol;
that's why there is no conversion between them... Cheers!
