If setting the network control panel to use only the LAN didn't take, just use the device manager to disable the modem.
I have two computers,1 is a compaq presario using XP home edition the other is a E machine using Home XP edition. I used the wizzard to set up a network and can get connectivity but the slave wants to use the modem to dial up instead of seeing the network? I get the icon network connected. Do i need to disable the modem on the slave? what am i doing wrong here?
