hostname

If I get the fully qualified computer name on a Windows server (2K3 or 2K8) using the GetComputerNameEx() API call, can I rely on that name to be unique on that particular domain? That is, can I assume that only a single active physical or virtual machine will have that fully qualified name at a given time?

As a second question: is it guaranteed that all Windows machines will have such a fully-qualified name?

Thanks for any help.
