Strange networking problem...

[Mike]

In our office, one of the users (who brings in own laptop) cannot connect to
network.
I can connect to same connection & can connect just fine.
Cable tester shows no problems, either.
I can take his laptop & connect directly into switch & it connects just
fine.
I had a new cable run & all worked fine.
He has moved to a new office & it's starting all over!
Any reason why mine, or any other computers can connect fine, but his
wouldn't?
Thanks-

When connecting, the NIC usually does an autosense on the network for
Speed and Duplex. Sometimes the autosense comes up with the wrong
answer. Try bringing up the Device Manager (start->run->devmgmt.msc),
double-click on the network interface card, click on the "Advanced"
tab, and there usually is a setting for "Speed & Duplex" which is
usually pre-set to "Auto". Try manually changing this to the speed and
duplex of your network and see if that helps.

HTH,
