Hi Steve,
thanks a lot :-) so in this case that i have a successfull configuration i would now implement an isc dhcp server under my centos 7 test environment. But how should i configure the dhcp server? I didn't find any howto. Only a skript from http://blog.michael.kuron-germany.de/2011/02/isc-dhcpd-dynamic-dns-updates-against-secure-microsoft-dns/
But is that the only way? And when it is the only way how must i integrate this script in dhcp?
Kind regarts
Markus

That looks as perfect as you're gonna get. And, it's working. Unless you want to try samba-technical or isc, I think this is the best you can expect, especially as it's working. Remember, the errors are written by coders and can at times have little bearing upon what is really happening.
I'm no expert on network topography. We chose dhcp because we wanted less work. For file servers we always use fixed IP. I'm sure that someone will chip in with some more concrete explanations other than sheer laziness;) HTH, Steve
