Connecting to a Windows XP machine

I'm trying to log into a Windows XP machine from my home IMAC using
RDC. The network administrator uses port 10443 for VPN and I am
assuming that this would be the same for RDC and that I would need to
add this ":10443" after my IP address in the connection line in RDC.
I've actually tried it with and without adding the specific port
number above.

Anyway, it does not connect either way.

I'm wondering
1. What does a network administrator need to do to set it up so that I
can get through the firewall to this Windows machine.

2. Is there some other configuration problem on my end that I am
missing. I turned off my home wireless and just connected the IMAC
directly to my roadrunner ethernet connection. But I've seen a lot
about port configuration and I'm just wondering if I am missing
something in my set up.

Any help would be appreciated.

Do you also have a VPN connection to your office network? If yes,
then you first make the VPN connection and then simply start the
RDC client, without adding a portnumber.

But it sounds to me as if you don't have a VPN connection, and are
just trying to connect over the Internet. Then you can't use port
10443, rdp traffic uses port 3389.
This port is most likely blocked in the firewall at your office, so
you would have to ask the network administrator to configure the
firewall so that it forwards incoming traffic on port 3389 to your
XP client. Note that the network administrator might be unwilling
to do this, since it would mean that *all* incoming RDC traffic
would go to your XP client (nobody else would be able to access
their XP client), and it's also a security risk, because everyone
(= the whole world) would be able to try to connect to your XP
client. You might have better luck asking for a VPN connection.
