[Samba] Win Clients and DNS

Mon Nov 16 13:22:05 UTC 2015

More explained.. 

Only my laptops get a DHCP IP. 
All my other computers have static ip. 

After the AD join, it does not matter if 
1) a desktop pc, when a static IP changes for a computer. 
2) a laptop gets a different IP. 
The PC always updates its A and PTR

So, in both cases my A and PTR records are changed in the DNS.

Maybe an firewall setting on you pc is blocking the update to the dns server or on the server you now allowing the dns updates. 

Can you have a look into that? 

Greetz, 

Louis
