MS TCP Lookback interface ?

hmm, not really sure what you are asking. but here is a shot.
Assuming that you are refering to Networking. The reserved IP address for testing NIC's is 127.0.0.1
this is your "loopback".
Therefore to test the connectivity and function of your NIC, you would, from a command prompt, type "ping 127.0.0.1"
Hope this is the information you were requesting.:)

yeah try the following

open the command prompt
in win9x is just DOS
or in Win2k/XP is CMD

then type this:

ping -a localhost

ping -a 127.0.0.1

also

ping -a (your isp IP#)

all of them should resolve to your name, say for example if your computer is call mikey

then after each of the previous test above

it should reveal mikey

here something like this

C:\>ping -a localhost

By the way the easiest way to find out what is your IP# is to run the command

IPConfig /all

:t have fun :p

By the way.... You will only get to see something like my example if your DNS has been setup properly :t
