Slow data transfer from domain server

Hi Everyone,

I have an annoying but quirky problem. I have a dell laptop with a broadcom
440x NIC and an intel wireless NIC.

Using the wired broadcom NIC, I copy data from a windows share in our domain
to the local machine which runs at around 400kb/s, but when I transfer data
to the server, it runs at normal speed.

Also, when I do the same with the wireless intel NIC, the copy from and to
runs at normal speed.

When I use the broadcom nic to copy data from a samba share, or a non domain
windows share, the speed is normal.

I decided to dive into the network monitor to see if something lit up. And
what I noticed is when I copy data from the domain share to the local
computer using the broadcom nic, I this pattern.

It has the SMB C read & X, FID and SMB R read & X, Read packets between 10 -
200 packets.

Then I uploaded data to the server via the broadcom nic, and these messages
were much less frequent.

This is also a fresh XP SP2 install with only the latest NIC drivers
installed. It was also happening on an XP SP3 install with all the latest
updates and drivers.

Does anyone know what the issue here is?

Thank you for any replies!
