Very slow file transfers

[Andrew Chalk]

One of the machines on my LAN is running W2K server and serves as a
multi-homed host connecting to the Internet. File transfers to and from this
server are very slow, about 1% of the speed of transfers between other
machines on the LAN. They all use the same switch and this particular
machine has been like this with both a 100MB and a 1GB NIC card.

Does anyone have any idea what might be causing this or any URLs that may
help?

Many thanks,

Andrew

I would try setting the NIC (both) to Auto-negotiate rather than hardcoding
full/half duplex or 100MB/1000MB. Have you tried that yet?

Thanks. The NIC Link speed/Duplex Mode is already set to auto-negotiate on
both cards.
I suspect it is an OS issue as this problem occurred before I upgraded the
internal NIC card.

Andrew, I have had some odd behavior with even some fairly new cards, and
recently with an older one I had your symptoms despite the fact that it's a
10/100 card it would only run at 10

I seem to recall it worked with W2000 but will not with W2003 and although
the driver is reported correctly I think it's somewhere in the stand off
layer between the OS and the driver or the driver and the card. I just put a
newer card in (Cheapest one I found at about $12) and that works fine.

Sorry this doesn't help you much but there do seem to be some odd problems
that can show up despite the fact that both hard and soft ware seem good.
