If you must obfuscate addresses, please do not use live ones for it.

Both are W2k, and if I run 'netstat -an' I get similar results:

[ Lots of open ports ]

I have some questions that I can't answer yet:

1.- What is the real meaning of all those ports open in both machines
at address 0.0.0.0 ?.

That means there are services listening on that port on all interfaces.

It's ok have to many ?.

That depends on what services you want to provide. Usually I'd say no.

2.- Who/what is listening in port 2751 (and in others ones) on server A?

That can be most anything. You'll need to find out what process is bound
to that port and what this process is supposed to do. TCPView [1],
OpenPorts [2], fport [3] or Vision [4] may help.
