Cat6 cabling problems

Hi there,
I have just had our house rewired and had my electrician install Cat6 cabling throughout (who unfortunately as it turns out, is no expert)
I have 7 rooms with Cat5e female sockets all coming back to my office where they terminate in 7 Cat5e female sockets. In the office I have a router which is connected to the female sockets via standard ethernet cables.

5 of the rooms seem to be working fine, but two rooms have a problem - I get connectivity, but I get the dreaded "Limited or no connectivity message."

So, I have two questions:

1. Should the wiring in the sockets in the office and in each of the rooms be configured in exactly the same way? (they are not - currently all the rooms are the same, but they are different to the office)
2. Do you have any good troubleshooting techniques to find out what's wriong with the two rooms that don't work?
I've scoured the net for wiring schematics, but I can't find any (i.e. how to wire the centre of the network vs the nodes)

Yours hopefully...
Jonny

1. yes The wiring connections should be the same at both ends.
the connections for cat5/6 must be as short as possible,with only enough twist removed for termination.

(The cat5/6 certification can only be applied if cables have been fully tested and a full technical report on each cable supplied by contractor)

2.If possible try a known working port and swap it to the problem cables if they fail ,check termination at both ends cables could also be damaged during installation

Ps yes I am a licenced cat 5/6 contractor(35yrs in industry)

Thanks very much - I'll haul him in and get him to change it.
What's odd is that 5 of the rooms work and yet they are not wired the same way as the sockets in the office where the router is located!
I'm confused...
