I have 2 computers both p4 and windows xp. I connect computer1 and my U/S
machine with Ethernet cable, computer tells me that network cable is
unplugged. When I use the same cable to connect same computer with router,
computer shows to be connected. Moreover I use the same cable to connect U/S
machine to computer2 it is again connected. In other words

Computer1 + U/S machine--- Not Connected
Computer1 + Router----------- Connected
Computer2 + U/S machine---- Connected
How can I fix this problem. Thanks.

Computer1's network adapter might be causing the problem. You need to
know what network "speed" the U/S machine is using compared to the
router (which is usually "auto" speed detected.)
 
Thanks fort the reply, Perhaps you mean if I set the network adapter to
autodetect it will solve the problem but I don't know how to do that.

Strictly speaking, when you directly connect two computing devices
using a cable, you need a special "Cross Cable". When connecting a
computing device to a Router/Hub/Switch/Modem, you do not.

What confuses things is that *some* of the newer network cards can do
an "auto-sense" and automatically reverse themselves when necessary,
eliminating the need for a crossover cable. In your situation, it
seems that your Computer1 does not autosense direction whereas Computer
2 does.

Try using a Cross-cable on Computer1 when connecting to another
computer.

HTH,

Hi
Auto detect relates to the speed of the connection, if you have No
connection there is nothing to detect.
P4 class computers are rather old computers and the NIC is probably Not MDX,
so (as posted by John W.) try a crossover cable.
