Hi all,<br><br>I have an NT 4.0, SP6a box with 2 3C905C-TX NICs, tcp/ip only. During the nt install, I configured both NIC's with a 192.168.0.x/255.255.255.0 address. I remotly back up the pc. All was great. <br><br>Next I changed one of the NIC's to 193.168.0.2/255.255.255.0 address to enable it to talk to a new private frame/relay network router, 193.168.0.1, that MCI/Worldcom had installed. <br><br>The problem is that after changing the address to 193... my remote backup hangs, I sometimes cannot sign-on the the NT domain, and have problems browsing the network. Even if I change the ip address back to 192... the problem does not go away. I have to disable the network card to get things working again. I have tried re-installing the latest 3com drivers and re-applying sp6a. Nothing works. I've worked with multi homed NT before and never had a problem!<br><br>please help,<br>bill
