You will have to install the drivers for it. Either use the disk that came with the card and install that then update the driver. Or use a different computer, download the driver put it on a flash drive and pop it in the server.
Keep in mind you'll probably have to activate windows, i've personally never used dreamspark so it might come activated... idk. and don't forget updates!
P.S.
I know it is a hassle but you really should be hard wired in. Not only do you get better speeds, your connection will be stable. If your server is two flights below you you will probably get poor reception anyway. If you arent tech savvy enough to do it, have a professional install a cable that runs from the router to the server.
