i just got this problem fixed, so i guess i'll post what i did in my particular case
i have a linksys router and onboard ethernet on my intel mobo.
basically, went into the router (192.168.1.1) and i went to the advanced tab. setup my computer as the DHZ (so basically just about everything gets forwarded to me now). to find your IP on the network go to start>cmd>ipconfig. if you havent already, you also need to go to network settings>local area connection properties>tcp/ip properties> and setup the information there manually so that your local network address never changes. you can get all the info you need to plugin to that by doing start>run>cmd>ipconfig/all .
havent gotten rejected since. blahahhaaha
