Routine Description:

    This routine retrieves the sid of this machine's account
    domain and returns it in memory allocated with RtlAllocateHeap().
    If this machine is a server in a domain, then this SID will
    be domain's SID.


Arguments:

    Sid - receives a pointer to the returned SID.

    SidLength - Receives the length (in bytes) of the returned SID.


Return Value:

    TRUE - The SID was allocated and returned.

    FALSE - Some error prevented the SID from being returned.
