I got two computer in lan connection using Windowsxp OS.
Also My boss got one computer in UK. I established remote
desktop connection between my lan computer successfully.
But my boss is asking me to control his computer from my
place. let me consider my boss's computer is Host and my
computer is Client . Anyway we both using windows XP OS.
While connecting ( Remote desktop connection) I am
getting the following error:

If I type the computer name in computer box I got,
The specified remote computer could not found verify the
computer name or IP address and try again. and

If I type the IP address on the computer box I got,
The client could not connect to the remote computer.
Remote connection might not be enabled or the computer
might be too busy to accept new connection
It is also possible that network problem also preventing
your connection
Please try connecting again later. If the problem
continues to occur contact your administrator.

Please help me sir.

Thanks in advance.

If the boss's PC is behind a firewall/NAT/router then you need to...

1. Forward TCP Port 3389 through the firewall/NAT/router to the private LAN IP of the boss's PC.
2. Call the boss's PC using the public IP of the firewall/NAT/router, ie. the IP assigned by his
ISP.

To forward ports on the Remote Desktop host (server) end consult the manufacturers documentation or
support web site for help...Note that you probably can not do that remotely, ie. configure the port
at the UK end.

Most, if not all, ISPs or corporations assigned IP addresses dynamically. That means that when you
or your boss start your PC the IP, as assigned by your ISP, is assigned from a pool of existing
addresses. The IP can, and most likely will change each time you log on. Your boss can find his
public IP by going to the http://www.whatismyip.com site. To find his private LAN IP he can run
ipconfig from the command line on his PC. For port forwarding to work correctly each time, its a
good idea for the boss's PC to have a static IP on his local office LAN.

I think you really need to talk to the local network administrators at your boss's UK site for help
determining his IP, the ISP assigned IP, how to forward the appropriate port though whatever
firewall/NAT/router they have at the site, configure his PC with a static LAN IP, etc, etc...etc...
