Question about UDP side of IPerf


Title: Message
Greetings!
 
After finding the IPerf software, I was excited as ever at the possibilities of this tool, but I've run into one snag... maybe someone has a workaround...
 
What our plan for IPerf is is to install the IPerf software as a service in our Windows 2000/XP environment.  Our Network Technologies staff can then use the software to test out the new backbone speeds, speeds to remote sites, and test links after users make the broad complaint of "everything is slow!"   I have gotten the IPerf software to install as a service under the windows platform, made it Automatic at startup, and everything on the TCP side works great!  UDP is a problem though... 

When attempting to complete the following command "iperf -c (dest. IP) -u" I get one of the following errors:
read failed: Connection reset by peer
or
recvfrom failed: Interrupted function call.
 
Sometimes both errors!
 
If I go to the remote machine, stop all Iperf services, and start a service via iperf.exe -s -D -u, then UDP works, but of course, TCP does not.
 
Now, when setting up the service under Windows, the only thing that will run is iperf.exe, no extra parameters afterwards.  If I start the service manually, I can input those parameters, but when the service is set to automatic, it will not save those service parameters, and therefore the UDP side fails.
 
What I am hoping for is that there is a way to start IPerf with both TCP and UDP (for jitter, very important to the project) running.  The difficult part has been having this be completely automatic so that testing can be done with no input required by the remote end.  Is there a way to have both TCP and UDP services running simultaneously under Windows with automatic startup? 
 
Thanks in advance!
