First, when I go to Start\Run and type IPCONFIG, the DOS screen flashes then disappears.

Second, I have a wireless router setup for my DSL connection. I have mt main PC wired to it and to other desktops and a laptop connect wireless. I added a second wired connection (there are sufficient ports) to debug & clean my folks PC. I show that I have a connection (via the local area connection) but only the fornt of the 2 Network PCs in the lower right corner (what is that toolbar called?) is blue, the other one remains black and I cannot connect to the internet. I tried the connection (swapped network cables) and my main PC connects fine. When I look at the connection, it says Sent is 552 and increasing, but the Received is still 0. I want to try pinging, but due to my first problem, I currently can't from the problemed PC.

Suggestions please.
