Correct Al, more worried that will be several machines just called "OFFICE1" which means they have access on all TABS, but your point for the other TABS is dead on the money

>Yes, a user with local admin privileges can change the machine's NetBIOS name. In practice, though, that's a PITA. If it's part of a domain, and it's not done by a domain admin there will be problems with the machine account on the domain controller. Even if it's just networked peer-to-peer you can potentially have problems like invalid security lists (who can access folder shares, printers etc.), loss of profile information if the old profile isn't migrated to a new name (with loss of e-mail, IE favourites and lots of other stuff that gets stored in a profile) etc.

>Long story short, changing the machine name can cause a lot of problems so it's highly recommended to never do it. So, when you combine that with the requirement that each machine on a local network must have a unique NetBIOS name, it's a pretty good way to individually track machines.

>BTW the unique requirement means that someone can't change a machine name from CANNING to WEIGHTING to try to get WEIGHTING's privileges, because the latter name is already being used on the network.
