try to dissect the ms cldap netlogon rpc flags bits.
the information comes from the samba sources and may or may not be reliable or menaingful. ms documentation in their knowledgebase says that the only really important part in the netlogon response is the sitename. (i have reasons to belive at least one of the flags, closest, is completely bogous) svn path=/trunk/; revision=10649
