r19759: Allow a join to occour against ncacn_ip_tcp again (useful for torture
tests).  The issue is that Win2k3 SP1 will not answer many LSA
requests on that port (I think this is as a security measure).

In this case, we need to skip ahead in the composite functions.

We were also checking the wrong variable to determine sucess/failure
of the LsaOpenPolicy2.
