I have set up a Windows Server 2012 Standard edition at home for learning purposes with the IP 10.1.1.2/16. I also have an ADSL wireless router which connects everything together and works as the DHCP server, with the IP 10.1.1.1/16. The Server name is in server_name.domain_name.org format and netBIOS name is as server_name.

When I try to join a client win7 PC to the domain_name.org domain by searching the domain as domain_name.org it says unable to find domain and if I try using just domain_name it finds the domain but fails to connect after entering username/password by giving the error Unable to resolve DNS name of the domain

I put a static IP to the win7 client with the DNS settings as primary:10.1.1.2 (server) & secondary: 10.1.1.2 (router) with default gateway: 10.1.1.1. Then searched and tried connecting to domain_name.org it worked really fine.

My problem is, I don't want to use static IPs for my clients. I suspect the issue should be with my ADSL router which is the DHCP server for the LAN. Please help me to solve this. Thanks.

It has nothing to do with static IPs. Your clients need to use the domain controller(s) for the domain as their DNS server(s). Your modem/router is likely setting itself as the DNS server. Change this setting there so that it gives your clients the proper DNS server as part of the DHCP configuration.


As, just as a side note: please read our faq. Home networking is off topic here.

  • Thanks for the answer, but I set the DNS in my router as 10.1.1.1 (itself) and 10.1.1.2 (the server) before asking here, still the error exists unless DNS settings are manually configured at client's end. I test this at home first before trying in the real environment, otherwise why would I ever have a server 2012 with a domain at home??? Only difference is im learning.

  • Setting your router's DNS is different than setting the DNS server that your router hands out to clients. The only DNS Servers that AD clients should use are DCs. If you read the faq you will see that everything at a home is off topic. If you'd like to ask why, that's what Meta Super User is for. – MDMarra Jun 2 '13 at 16:54
  • Thanks a lot, this is really helpful.. specially pointing me to Meta Server Fault :) Sorry and apologies for troubling you all with these minor matters. – JRulz Jun 2 '13 at 17:35
