Maybe flush your cached DNS cache table?<br />

Thanks for the reply.<br />
<br />
I ran the command: sudo killall -HUP mDNSResponder, it asked me for password and I entered it. It didn't give me any confirmation or status, just terminal prompt, after I tried to ping the name again. Still no luck resolving the domain.local...

Thanks for your comment!<br />
<br />
Nothing worked :( I ended up editing the hosts file! I still don't know what is causing this but at this point, I am so fed I DONT EVEN CARE!

<div>
That's actually not the correct way to fix it as that will cause problems when you move to other environments. &nbsp;What do you use for DHCP? &nbsp;You need to set the DHCP server to correctly dole out the DNS information to all your DHCP clients.

<div>
Yes I 100% understand that however what can I do? I statically assigned a DNS server and Mac OS is completely ignoring that assignment.<br />
<br />
I am only getting IP, subnet, and gateway from DHCP, DNS is assigned statically.

<div>
DHCP servers normally set DNS for the DHCP clients as well. &nbsp;You must have something set incorrectly on your DHCP server, or you somehow block the DNS port 53.

Hi guys,<br />
<br />
I have a small network with 5 PCs and 1 iMac. PCs are Win7 Pro and iMac is OSx 10.12.4 (sierra).<br />
<br />
All 6 computers have the same DNS address. 10.0.1.25 (statically assigned) and all the computers are hardwired and on the same network.<br />
<br />
From the PCs I can ping and resolve activedirectorydomain.loca<wbr />l to 10.0.1.25 but from the Mac I can't.<br />
I get this error ping: <b>cannot resolve: activedirectorydomain.loca<wbr />l: Unknown Host. </b><br />
<br />
From the Mac and from the PCs I can ping 10.0.1.25. So I think this is a DNS issue. It's almost like the Mac is not accepting my statically assigned DNS address for some reason.<br />
<br />
Any thoughts?

iMac not resolving DNS

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.
