Question : XP home not connecting to other computers...

I have a small network of 4 computers.  Win98, Win2000, and WinXP(home).  The WinXP home was recently added to the network (Dell 2400).

Problem:  WinXP can not access any of the other computers files or printers.  I can map it, other computers can be seen from my network place but once I try to connect it would give me an error:
"\\server is not accessible.  You might not have permission to use the network resource.  Contact System administratir....   The network path was not found."  This happens when I try to connect to the win2000 computer (is a server computer running under a workgroup).

"\\sharename is not accessible..........Same...  The specific server cannot perform the requested operation"  This happens when I try to access the win98 computers.

More info: the win98 computers can only goes as far as seeing the shared files(which takes a long time) on the winxp computer.  When trying to open the file it gives the error

Pinging = DONE (all computers can ping each other)
Checked workgroup name = DONE
Turned off firewall = DONE
Checked IP Address = DONE
Enable NETBIOS = DONE
Enable guest account = DONE
Tried = net use s: \\Servername\sharename /user: domainworkgroup/logon
Tried = Net Use X: \\servername\sharename /Persistent:yes
