Error loading tcp/ip

If you was looking for help from other members of TR, then I'd suggest you give a little bit more information, like:
What system (hardware, operating system, network, type of internet connection) do you have?
What where you trying to do?
What happened?
What where you doing when (or just before) this happened?
Did it work well before?
What have you tried?
etc.

Otherwise, good luck - you'll be on your own with your problem.
