Client's offices are entire second floor. Major power spike took out surges and 2 computers. Since that time, I cannot get a connection on any system with their existing cabling (it was run open in a dropdown ceiling).

Does anyone have any "Tech Notes" or narrative on what happened to this cable so that client can charge building owner for replacement?

Are all these systems connected to a common switch? If so, chances are the surge took out the switch as well.

You need to actually test the cable runs before assuming they are bad. The surge would have to be powerful enough to literally melt wires (or at least the insulation) before it would take out ALL cable runs. Test the switch these computers are connected to.

In addition to the switch / hub, you may need / want to unplug ALL PCs from the network.

Assuming the cabling is fine, now plug PCs back in 1 at a time until you find the PC with the bad NIC that is locking up the network.

The only other thingI can think of, is to disconnect the cable runs for the 2 PCs that were damaged at the switch in the unlikely event that the surge damaged the cable itself.
