You cannot connect new laptops to the networked printers etc at logon I'm afraid , if only life was that simple
- they have to be set up by tekky man ( nincompoop that he is ) - and I'm afraid the backslash would appear to be essential in this process.
However they have now gone away to come up with a workaround ...to be continued tomorrow

Basically, in a "proper" networked environment, users access and accessibility would be centrally controlled - ie shares on servers, email, internet access, printers etc., would be allocated by their logon. This makes life simpler for the administrator and the user. It is also more secure and safer.
Your "techies" would appear to be a bunch of amateurs. They are also slow and very un-professional, even by my standards.
Twould seem that they should be shown the door.
