Im not sure what surfcontrol does, but when I want to analyze my network traffic, I need to plug Directly into the Console port on the Switch.

A switch only sends packets to the node that needs it, wheras a Hub sends all the packets to all the nodes.

If you Server is plugged into a switch then the only traffic it will see is its own.
If you need to see other traffic you need to conect directly into the switch with a console cable.

On your switch you should have a console port, where a laptop can directly conect into the switch using the software that came with the switch or just by using HyperTerminal, a Windows program.

you then have direct access to the switch using the Laptop. I'm not sure what sort of program Surfcontrol is, but this is worth a try to see if you can then see what other traffic is on the the network.

but, being a specific program to sniff traffic, maybe there are some settings on the switch that you can change to allow you to run this program from the server, otherwise theres no point in having the program!
 
Also, the program may look for a Network Conection to sniff the traffic, therfore the console cable may not work!!
so everything i've said will not work! :-s give it a go anyway, it cant hurt
