                  nonnull. If the user cancels, return FALSE.

   Internals:     This dialog and code is currently not an exported
                  routine regularly found on any user's system. Right
                  now, we dynamically load and call the routine.

                  This is definitely temporary code that will be
                  rewritten when NT stabilizes. The callers of this
                  routine, however, will not need to be modified.

                  Also, the Domain/Computer dialog currently allows
                  a domain to be selected, which we cannot use. We
                  therefore loop until the user cancels or selects
                  a computer, putting up a message if the user selects
                  a domain.

   Assert:        lpszComputer is at least MAX_SYSTEM_NAME_LENGTH + 1
