Networks
In active network some times Patch Cords doesnt work in some nods, but in other nods it works.Some times the working node stops,and changing Patch Cord it starts again.But the some cable works in another node.
WHY?

This problem comes due to negligence while making patch cables and punching RJ45 Connectors.Some connectors are pressed too much due to which some pins in the connector lost connection with face plate.which creates problem on later stage when the connections are gone loose or old.
While making a patch cable you have to ensure that all wires in network cable are trimmed equally and should touch the pins to last of RJ45 connector.
RJ45 connector should not be puched with extreme force.

I'd like to add to the above that you may want to doublecheck your lengths. I've run into some occasions where long runs simply don't want to work at 10/100Mbps. By throttling them down to 10Mbps HD, I've been able to get them working again (but then you're going to need a switch with this capability, like the 3Com 3300).
Electrical conduit, fluorescent lighting, and such can affect your signal if your wire is passing by this type of equipment.
