Consider the following scenario: Each office has two Cat5e ports (A & B)and there is an 'A' Patch panel and a 'B' patch panel. When PersonA is plugged into port 1A and PersonB is plugged into port 28A they can see each others computer screen. If PersonA is online working and PersonB comes in to log on -- when it gets to her login security screen, it pops up on PersonA's computer screen and PersonA can see what PersonB is doing and vice versa. I had PersonB plug into port 28B and the problem stopped.
Can you explain this phenominum? It this is crosstalk issue or how could this happen with the installation of new Cat5e wiring?
