Dear Elmer,

This issue is a little outside the scope of this particular Helpdesk. We are much more prepared to address physical infrastructure (cabling) related issues than issues with active equipment, which is what appears to be the case here.

Anyways, I will try to answer the question to the best of my knowledge and maybe you can find more help in the Ethernet discussion group.

Your PCs are all sharing the same Ethernet bus and problems with one client are affecting the rest of the clients. There may be couple things: one of the client PCs can be broadcasting IP packets thus using too much of the available bandwidth. There could also be IP address conflicts in the network - two or more PCs can have same IP addresses. I suggest that you get a copy of Ethereal (network analyzer software) and run it on one of your PCs to find any problem. You can also try to unplug PCs one by one and find the one that's causing the problem and keep it unplugged or have a professional look at the PC.

Good luck!

Dmitri Abaimov, RCDD
