Hi every body

I installed active directory in my server, and my server ip is invalid in range of 172.16.0.0 with subnet mask 255.255.0.0 after some week i get an valid IP address for my network, and i add this IP in other network card of my server, but now my dns root hints is disable, and i can not use my dns for my local network to connect the internet.

then I used the other dns such as 192.9.9.3 and now, speed of my local network is very very very slow, and users can not login immediately such as past

please help me how can i active my DNS root hints and update it

Thank You

Remi

I think you would either need Internet IP addresses for ALL your devices OR you could set up a router to go between the internet and the LAN.

If your ISP only gave you one Internet IP address, and you have more than one device, then you have to use a router.  The WAN port of the router would have the Internet IP Address assigned by your ISP, and all the internal devices could have private IP addresses in the 172.16.0.0 range.

All your computers inside you LAN would use the internal DNS server for their lookups.  You would set-up the DNS server to forward any requests that are not in its database (such as yahoo.com) to your ISP's DNS servers.

[EDIT: Fixed Typo that changed meaning! ]

best way to go about it is dont worry about using a second nic in the server because it will slow your network down unless step up correctly.
Like wistex said use a router to access the internet & also make sure you have your ISP dns servers inside the router.
