I am managing an Windows Active Directory network and have several mac machines that need to be added in. Our office has a LAN (with no internet access) to allow users to access local resources (File Server, printers, etc). But to connect to the internet, we all use the building's WiFi connection.
I was able to setup one of the Macs to connect to the active directory domain and users are able to authenticate through the AD server and access shares on the file server as expected. However, once I add the second network for the WiFi connection, users cannot access the internet.
The only way I have found to get the internet to work is to Change the Service Order of the two networks, such that the WiFi Network has priority. But when I do this, and log out and back in, then the internet works, but the iMac can't see the Active Directory Server and doesn't show login options for network accounts.
I did a couple of tests to further characterize the problem.
If the LAN is set as the first network in the Service Order, then I can ping computers on the LAN by their IP or hostnames, but not any WAN IPs or addresses. I can also ping the domain server by the FQDN (Fully qualified domain name - like local.foo.com) and it works fine.
If the WAN is set as the first network in the Service Order, then I can ping computers on both the LAN via their IP addresses, and the WAN servers via IP or hostname/web address, but the iMac can't find the active directory server on the LAN to allow network logins. Also in this case, I cannot ping the domain server by its FQDN.
Based on the above, I suspect that there is a DNS issue here. Is there a way to allow the Mac to resolve the domain server when the WAN network is first in the list? Or alternatively, Is there a way to reroute all internet traffic through the WAN when the LAN is set as the priority network?
Thanks,
