Low Network Utilization

We have a 2003 server being used as a standalone web server and have recently
(last 2 weeks) noticed that the transfer speeds have slowed down to sub
100kb/s where before we were getting 200kb/s +. When testing the speeds we
have used a 60MB zip file and tried transferring via HTTP using IIS and FTP
using an FTP server called Serv-U both are showing the slower speeds.
I have been watching the network utilization on the server whilst these
transfers are being done and its not getting over 1% (100MB connection).
Would I be right in thinking that it should go a lot higher? Any ideas on
where to look on fixing the problem? I have already looked at the event, FTP,
HTTP Err logs and nothing is appearing there.
From the logs the only changes to the software on the server that have
occurred since the beginning of February are the MS Updates. Looking forward
to some help. TIA
Antony

Any modern computer should be able to do >95% on a 100MB LAN connection.

Do you have any firewall or network anti virus software on the server or
test ws? There's a bug in the ms firewall that chokes it on 100mb or
Gigabit ethernet. http://support.microsoft.com/kb/842264/en-us

I was only gettin ~15% through put on 100MB ethenet between winxp computers
before I disabled the firewall service. After words I get ~98%
