One new computer on LAN running at 10 mbit

[Mike Barry]

I have a rather puzzling problem...at least to me it is.

The LAN is a Win2K server--- DNS, DHCP, DC. There are
about 8 or so workstations, most of them running Windows 98.

Tonight we replaced 2 computers on the LAN with new
Dells. The 2 new Dells have XP Pro.

Everything is working fine except that the 2 Dells were
running at 10 instead of 100 on the LAN. Network browsing is
fine, and Internet browsing is fine as well.

We went hunting for things that could slow down the
connection, and found a really old Jetdirect and disconnected
it.

Now, one new Dell is running at 100 but the other one
is still running at 10.

The one thing we didn't do (because we couldn't) was
to swap out the CAT5 cable on the troublesome new Dell.
We'll do that tomorrow, but if that doesn't work, does anyone
have any suggestions?

I tried switching the NIC (it's an onboard NIC) to
100/Full Duplex and it stopped working. It's set to
Auto now and is back to 10.

Any help would be appreciated..

Thanks!

Mike

The machine you are still having problems with, is it
connected to the same router/switch as another machine?
Some routers/switches if they are not configured properly,
will give the clients the speed 10mbit. I would (As you
said you will do), try another cable and see if the
problem persists. You can also try to connect the faulting
machine with another machine directly (via a cross-over
cable), and see if it starts to operate at 100mbit instead
of 10. This will tell you if the problem is in the machine
or your network.

Hope this helps!

I would assume yes. I didn't take a peek at the
router, but I'm fairly certain there aren't 2 switches in
there. All the other clients are running at 100mbit, so
I doubt there are 2 switches.

It's worth a check, though..thanks.

Check the NIC properties and make sure you've locked down the speed and
duplex settings. Do not use autosense anywhere - no workstations, servers,
or switches (if the latter can be managed).

Well, as it turns out, the problem isn't that one workstation
is going at 10, it's all of them *except* for one which is going at
100.

I didn't actually go to the workstations myself and check.
The person working with me either stated the problem incorrectly
or I heard her wrong.

Anyway, given the office's equipment is rather old, I'm sure
there is a hub or a switch slowing everything down in there, and it
should be easy to fix.

Sorry about the mistake, and I do appreciate everyone's help.
