Using patch panel fields and patch cables versus running cat5e and field crimping a modular RJ45 end
I have a heated debat going on with my IT folks regarding the use of patch panel fields and patch cables versus running a cat5e cable and filed terminating a crimp style rj45 end. I know what the standared dictates but I would like some more reasons patch panels and patch cable should be used as our IT folks insist that using patch panels just creates an additional fail point and is not a better solution than using crimp mod ends and connecting equipment directly without a patch cable or panel in between.

I would tell you what I think of your IT folks, but I don't want you to rate this response as IA :-)
Yeah, they have a point. Wiring point-to-point does cut down the chances for failure....provided they used the proper plugs and don't plan on moving them around. It gives them job security because you have to label each cable and when the tags fall off, only they know where the cables go. Plus, a structured cabling system give you, well, STRUCTURE. You're not at the mercy of the guy who "crimped" some imported 8-pin plug on a piece of wire. Wait were those solid or stranded wire plugs? It may run 10 Base T, but it is unlikely that it will run 1000 Base T.

Do you mean that you tested the patch lead that connects the patch panel and the hub?
The RJ45 connection at the workstation (one end) and the RJ45 connection at the patch panel (at the other end)?
If these checked out OK then the RJ45 connection at the hub could be faulty, try a different port on the hub, do you get a link light?
The LAN card in the conputer could be faulty, try another computer at the "faulty" workstation to check the network connection.
How are you connecting to the port in the back of your router? if you have crimped a male plug on to some UTP cable then this may be the problem. UTP cable has a solid condutor and needs a different male crimp plug than UTP patch cable, which has stranded conductors.
I suggest you connect the UTP cable between the office and the loft to an RJ45 wall or surface socket in the office, use a terminating tool designed for the make and type of outlet you use, i.e. if using an ADC socket use the ADC termination tool. The sockets are designed for solid cable and have a colour code for you to follow. Then use a factory terminated patch cord between this socket and the router port.
I assume you have terminated the cable from the office onto one of the patch panel ports and want to use a patch cord to patch from this incoming socket to the sockets that are terminated onto the cables going to your other rooms. If you have access to a laptop connect this directly into the router port and ensure you have an internet connection, then plug the patch cord connecting the loft port into the router and take the laptop into the loft and ensure you have a connection at the incoming port on the patch panel. If you get the connnection there then use a factory patch cord to patch to a room you would like a connection in and then take the laptop to that outlet and ensure you have a connection.
If you want to run outlets in multiple rooms without re-patching every time then you will need to have an active switch in your loft and connect the port from the office to this and then patch out of the switch ports to the various room outlets.
RJ -45 is a type of connector used on cat5, cat5e....etc cables to connect networked devices...the RJ stands for registered jack but there is really not much you really need to know about it....a RJ 45 JACK is a little bigger than a telephone jack, you'll notice the female type of input on your computer or laptop and the male end will be on the end of the cable that goes into this jack....hope this helps
Unless you have a RJ45 crimping tool you are stuck with having to ask someone who does have one to borrow it, honestly if you know someone with a crimping tool then ask them to perform the repair.
If however you have the tool for a straight through cable (most common)
Holding the plug upside down (catch towards the floor) and the pins furthest away from you I use the following layout;
orange white (furthest left hand side)
brown brown white (furthest right hand side)
slide the cables into the plug held in the position describe above, then check the order of each wire once more using the crimping tool to "crimp the new RJ45 connection in place.
Basically as long as you hold the rj45 connector in the same position the wires should go into the same corresponding position at each end.
