i've got problem with 2 LAN Cards

i'm using winxp sp2 and i've configured two LAN cards in my PC. one lan card is on local networking(with ip series of 172) and other lan card is on static ip(with ip series of 122). the problem is that i can't access my local network when the second lan card with static ip is enabled although net is working. but when i disable my lan card with static ip and restarts the PC.i'm able to access the local. i want to access them simultanously plz help as i've changed 3 PC. but problem is still there
