Is it possible to change a machine's host name? I noticed there is a "hostname" macro, but it seems to only read the info, not write to it/change it.

Another method would be to write a new hostname straight into the registry, correct? I'm wondering if I can write to the registry using a variable, such as @userid? I'm thinking of doing something similar to the method suggested under the thread "change computer name with kix." Here it is, except I would use the part of the registry that contains the dns stuff, and I would LOVE to be able to set the hostname value the same as the user name.

Is there any way to do this?
