Can you get some decent pictures of the back of the RJ45 jacks at both patch panel and remote sockets. Host them on a suitable site and then provide links to here.
If you have two sockets at a remote location, link them together and then, at the patch panel, try a cable tests and see what the result is.
Does your laptop/PC have a network cared test facility? Broadcom for example include one in their control suite software which allows testing the connection and the cable including Distance. In my case the PC reports the length and I can also use my switch to do the same in the other direction and the lengths match within a reasonable tolerance.
When you punched down the IDC connections, did you ensure everything was fully home - a double punch is often best.
