Ok, I have 2 XP professional computers. One has 2 network cards (Intel 100+ Pro) and the other 1 of same. Im using a Crossover cable to connect the 2 networked computers. My network protocol between the 2 machines is the default TCP/IP (btw- is netbios over TCP/IP more stable and faster on or off?) The Computer with the 2 Cards has 1 Connected to net. ICS is enabled and working great. network shared folders show up.. Im able to access.. everything seems great. until I try to download files. If I download smaller files from the one computer to the other (about 10-20 megs) everything works fine, however if I try to download larger files (multimedia stuff) I keep getting pop-up ballons by my clock telling me that a "mshome connection unplugged".. the time to dl on the file starts to go up. then the message disappears for about 10 seconds and then here we go again. My first thought was line quality, but Ive tested it by accessing the net through the network and running tests, playing games, ect.. works great. Im at a loss. Any help would be greatly appreciated. Thanks in Advance. H.
