OK not entirely a hardware question, but bear with me.

I am planning on setting up a gigabit backbone to the FITHLan network for file and dedicated game servers (not that we need it, but because I want to).  Until then I just set up a new file server and the mobo has dual 100Mb lan ports.  Is it possible using winxp pro to multiplex those 2 lan ports giving double the bandwidth to the file server?
