How do I add Win2K PC to XP Network?

I've got a small home network with 3 XP PCs running behind a wired router (cables throughout the house).  Those three all have shared folders and shared printers and scanners.  All is well.  One thing I did discovere is that in Zone Alaram (runs on all 3 PCs) I had to add each PC to ZAs Trusted Zone (i.e. ZA on each XP PC now has 3 Trusted Zone Host/Site entries, one for each XP PC).  That network works just fine.  

I have a 4th PC runing Win2K that I want to add to the network.  On that Win 2K PC I've joined the workgroup.  But I can't see anything on the network from the Win 2K PC, nor can I see with Win 2K PC from the XP PCs.  Does anyvody know what I need to do to successfuly add that Win2K PC to the network?

Thank you

enable NetBIOS over tcp on all machines
and make sure the server and workstation services have started
also make sure they all have valid ip info (same network, subnet, etc) and no firewalls are interfering
looks like it is your zone alarm firewall.

Allow your 2000 IP address in the other machines and vice verser

I forgot to mention that I am running XP Home.  It seems to me that in that case then ther is no TCP nor NetBIOS.  Is that correct?
