Bit stuck with these...
Firstly, can anyone think of a way to remotely change the DNS servers on a PC. I'm thinking of something built into Windows rather than a 3rd party tool. It's something I do everyday and it would make life easier if I could just issue a command.
Secondly, how do you delete a service? I've Googled and found nothing. It must be possible

Sometimes I want to install VNC and find I can't because another version already exists (as a service). Need to remove the service so the install can complete. I'm wondering if there's a command or whether it's a registry hacking thing.
