need to justify here the root cause

publictoiletbowl

hi community

i have active directory with the ip
192.168.100.254
255.255.255.0
gateway 192.168.100.1
primary dns 127.0.0.1

but the main issue all of the sudden my AD unable to resolve any external hostname but it can ping any server ip such google or any server outside the only problem cannot resolve the hostname so my AD no browsing but if i change the AD IP configuration to DHCP it works . need to justify if this issue related or conflict to pfsense local dns 127.0.0.1 since the AD dns has same 127 too? is there anyone can point me in the right direction how to solve this issue?

thank you

@publictoiletbowl said in need to justify here the root cause:

dns 127.0.0.1 since the AD dns has same 127 too?

127.0.0.1 is the local host, all machines everyone on the planet use 127.0.0.1, its their localhost IP. There is no conflict.

Your nslookup is asking the machine itself to lookup yahoo.com, is a dns server even running on that machine?

Where does the dns on that machine point to for dns? Is it resolving? Or forwarding?

@johnpoz hi sir i solve the issue the root cause is in the DC properties was assigned the existing dns ip before so i change an new dns forwarder.
