Weird! Networking 2 computers using crossover cable & ICS

I am trying to network 2 notebook computers, using a crossover network cable.

Computer A:
Windows 2000 Pro
Has USB connection to ADSL modem
Internet connection has ICS (sharing) enabled

Computer B:
Windows XP Pro
Is registered on a domain, for work purposes (I'm attempting to connect these 2 computers at home).

Now here's where it starts getting really weird...

When the 2 computers are connected with the crossover cable, they can see each other - but only to a limited extent:
- I can map to shared folders on the remote computer BUT I am required to provide a user name and password, even though the guest account is active, enabled and has permissions.
- I can view the remote computer by name in the windows explorer.
BUT
- The computers cannot ping each other.
- While computer B gets its IP address from the DHCP server on computer A, and has 192.168.0.1 as its default gateway, it cannot communicate at all with computer A, either by IP address or by computer name.
- Naturally, any attempts to use the internet connection share (which is really what I'm after) are in vain.

Anyone have any idea what to do with this?

From computer B, are you able to ping its own IP address? Try pinging 127.0.0.1 to make sure TCP/IP is fine.  Most likely you are able to browse the other computer and map shared folders because you have netbeui installed also.

Type ipconfig /all from a command prompt and verify that the IP addresses and subnet masks are correct on both computers.

I can ping myself from both computers (ping 127.0.0.1).
IP addresses and subnet masks match on both computers (192.168.0.1 and 192.168.0.192 IP and 255.255.255.0 subnet).

I think a large part of the problem is the fact that one of the computers is on a domain.  Let me try see what happens if I rename the server computer's workgroup to the same name as the client's domain...

That should not have any impact on TCP/IP itself.

Are you running DHCP Server on Computer A or do you mean it receives a DHCP address from ICS?

Be sure to disable any firewall software on either computer if applicable.

BTW, I should add, for anyone else reading this:

THE MAIN PROBLEM WAS:
Windows XP didn't have NetBEUI installed.  I just had to find a driver for NetBEUI, and everything was fine after that.
