I have a 2 computer 100mbps ethernet network on a 5-port hub.  The server is NT4Server and the other computer is running NT4Workstation.  I was successful at setting up file sharing and such, but am unable to ping either computer from the other computer. When pinging the server from the workstation I get the message that "Destination specified is invalid", that is using the actual IP address of 200.150.100.0.When I ping the server using its computer name, 'PHOENIX', I get the message, "Bad IP address phoenix". When pinging themselves the results are correct.  I have NetBEUI and TCP/IP installed on both machines.  I set up the network 'according to the book'.  What can I do to get this simple line of communication to work correctly?? Is there another networking service or protocal I need to install to get this to work??
Thank you for your insight...

First of all these to computers must be a part of one subnet.
If you are using one one computer IP 200.150.100.0 (which is also not good better 200.150.100.1) and subnet mask 255.255.255.0  than the second computer can use IP 200.150.100.2 to 200.150.100.254
I tried this and it fixed the problem
If you want to use also name of the computer than in winnt (system root) directory winnt\system32\drivers\etc you have to find file hosts and specigy that for example you "phoenix" computer has IP 200.150.100.2 than you just add the line
"200.150.100.2               phoenix   #phoenix computer"

The IP address of 200.150.100.0 is a calss C network address and can not be assigned to computers and that's why you are getting the error (Destination specified is invalid).
The error "Bad IP address phoenix" is probably because you have edited your hosts file and entered the invalid IP there.
If you haven't done so then broadcasts will lead to the same problem.

Here is my solution:
1- Give your client (phoenix) a proper IP address that is not used by any other computer in your network.
(200.150.100.3) for example.

2- If you have edited your hosts file make sure that the new changes are reflected there.
