Local Area Network problem

I am running a small office network using a 3 com hub.
All of my computers can access the internet but my local
area network has disappeared from all machines. Some of
the computers recognize themselves but no one else. I have
been running this network for several years with no
problem until last week. I am using NETBUI and TCP/IP.

Any help would be appreciated. Thanks,

1. Get rid of Netbui it is too insecure and impossible to troubleshoot.
2. Firewall ?
3. Antivirus ?
4. etc.
