hi all -
i've got three pc's in my house. one hardwired to my dsl, the other two connected wirelessly.
i recently picked up starcraft and would like to network two of my pc's together so i can do a head-to-head thing.
however, when i tried i received some sort of error - of course i didn't write it down so i can't tell you what it is.

it had something to do with not finding an ip compatible network.
so, is there anything special i should do.
since the two pc's are in one room i suppose i could just buy a null-modem cable (at least that's what the program said) but i have no clue what that is!
i really don't want to go through battlenet if i can help it - it seems like that would be an inefficient way to do this.
anyway, any ideas?
thx!
ted
