[Samba] DNS (Bind )update via external DHCP ISC

[L.P.H. van Belle]

Hai, 

Did you set "auth-nxdomain yes;" in bind config ( for me on debian named.conf.options )? 

And in windows, this should be enabled by default, check but check if .. 
'register this connection ' s address in DNS' is selected and 
'Use this connection ' s DNS suffix' in DNS registration is also selected

Anything in the windows eventlogs. 
( clear eventlogs first ) 
Run : 
ipconfig /release 
ipconfig /renew
gpupdate

Now, what is in the windows event logs. 


Greetz, 

Louis
