    I would use Virtual Server for this - although it will place a resource strain on the Server itself (unless it's a good spec)

    As an addendum: it's a free download, but you will need to buy another Windows Server licence.

    I'm gathering you mean a sub-domain..
    any how. it's not possible on the same server .. you could virtualize the servers on 1 hardware device but you cannot make a machine domaincontroller for 2 different domains in active directory.
    I would of course also be a mayor security breach as a domain controller "owns" the domain and thus the server and so this would mean that an administrator for either domain could corrupt the ad very easily..
    a sub domain is build for security reasons mostly (an other good reason would be replication but even that can be fixed without a subdomain.)  and therefore it would be wrong do even try doing it if it were possible.
