Why my network (Lan connection)not working on one of my office computer, but on other was working??
on that computer just working if i in-out the LAN cable from my CPU. please help.

Does the non working pc get an IP, does it have an active connection? IF you swap cables does theproblem follow the cable or the PC?

Can the pc ping its own ip?
Can it ping the ip of the working machine?
Can it ping the gateway?
Can i ping beyond the gateway?
Can it ping by hostname (i.e. www.yahoo.com)?
