sorry for beeing unclear. I ment the point some posts above (yesterday).
When I try to join a win 7 machine to the dc i get an error, that the dc was identified, but that it couldn’t connect. And windows suggests, that there is something wrong with DNS or that the DC is not connected to the network at all.
I tried the command from samba with “host-t SRV _ldap. _tcp.ns7a3.at” and others and get a correct answer.
So i was asking myself, if i should be able to ping the dc itself or anloy the host-machine.
thanks. Ralf
