Really slow server to client transfer speeds

We recently installed 2 new servers at a clients location replacing an aging
Win2k server and a Mac email server.

The servers both have brand new Xeon processors with 4GB of ram 2 raid
arrays one for sys and the other for data.
Bother servers have GB NIC's and a brand new Dell GB switch was installed.

The servers are really under a minimum of load at all times.

Heres the problem.

The client has been complaining about slow server speeds.

As a quick check I ran a test by downloading a 512mb file from one of the
servers to a clients machine with a 100Mb NIC. The file transfer was as slow
as could be with the net utilization on the client side staying around .19
yes that's .19

I then ran a test from server to server with the same file and it happened
quite quickly.

My first thought was probably a bad cable or the NIC in the client machine
was on its was out.

So I ran the test from another client and got the same results.

I then ran the test from client to client and the speed was as quick as
could be expected for ATA drives and a 100Mb NIC.

Does anyone have any idea of what could be wrong or what I should test next?


Thanks,
Bryan

A little more info about this problem.

Server to client seems to be decently fast also.
