Anyone with an a/c in my Domain can gain access to my laptop?

My University’s putting us all (students) into a domain. The domain’s name is Campus. Thing is we all have personal laptops… I can access my friend’s laptop with my domain username right? Then, isnt this a stupid idea?

They also want to use Microsoft Live Communications Server 2005…and I am worried about the built in archiving features that it boasts of…

My recommendation would be a Jabber Client and PHPbb3…

Please tell me if the college is on the right track…

Thanks,

Reddox
