I've run into a problem I've never seen before. I have a total of 5 machines, some W2K, others XP that receive an IP via DHCP, have proper DNS, WINS, gateway and subnet assigned yet are unable to access the LAN or Internet. I have tried multiple replacement NIC's, the problem continues. I have reinstalled all networking components, tried Winsock repair utils, different NIC drivers, different patch cables, different LAN ports. The only way I've been able to fix it so far is to wipe the hdd and reinstall a fresh OS. An OS repair does not fix it. There has to be another way, please help! Thanks!
