what ya did didn't fix the problem

what ya did didn't fix the problem ... first ... phone hang up without any reason ....
then did a remote patch of a client PC , and they said the CAD PC as slow as before.

I always suspected those slowness problem at that d0emed site was due to a cabling problem. they use phone patch panel instead of data patch panel.

this could give rise to funny problems like excel sadden hung-up.
