To clarify, i dont want them to have access to anything at all other than the business websites.
(IE: I dont want them messing about deleting files from windows for a giggle.)

To answer whoever asked "Why cant they just ask you?"
We are extremely busy and often customers will spend 20 mins with us asking what can be chipped, and going through a whole list of cars they "Could" buy. The worst culprits are the friends of people who are waiting to have their car done, so while we are trying to work on it, they drill us to see what can be done. Understandable, but time consuming.

Whilst this is good from an enquiry sense, its very bad from a time management sense, so i thought i will put our websites
http://www.motorsport-developments.co.uk/ http://www.evolutionchips.com/ online in reception so they can answer all their own questions via our very powerfull application database. http://www.evolutionchips.com/chipsearch.asp and maybe even generate some business.

The database is another reason it cant be browsed offline as easily as some websites, as its not all just HTML, theres a lot of background operations with the databases.

Thanks for your help so far folks.
