I'm assuming that means that BIND (named) is working and doing what you want with regard to the local / internal domain name. With these assumptions, it seems to me like BIND (named) is working and that it is likely not configured to allow clients to perform recursive queries. Assuming this is the case, you need to change the allow-recursion parameter to allow the LAN clients to perform recursive queries. This is predicated on the system BIND (named) is running on being able to access the internet to query external resources on behalf of the LAN clients. If someone knows a guide to help, I'll be glad to know. Please reply if any of my assumptions are wrong or if you have other questions. Thanks. You're welcome. -- Grant. . . . unix || die

I'd avoid using the .local TLD due to RFC 6762. You might also consider whether mDNS is actually the easiest solution to your problem. > I've realized the network PC's did not find the DNS address, only the > localhost can find it, when I force the DNS, the client PC cannot access the > internet anymore. I don't know what you mean by "force the DNS" but in general most OSes will just have a list of DNS servers that they will pick from either in order or randomly, and without regard to what the TLD is. So, you'll probably want to tell them to use your internal DNS server as the only DNS server. This means it needs to be authoritative for your internal domain and resolving for the others. If you used the .local TLD then you might also be running into issues with conflicts with RFC 6762. BIND is capable of doing the job - I have it set up to resolve an internal domain and outside DNS. I have BIND set up to forward first to Google DNS, and then added my zones to it. -- Rich
