New DC installed, nslookup still shows old DC IP

Hi,

With a computer on our domain, when I use nslookup, it is still attempting to query the old DNS IP address, and isn't attempting to query the secondary at all.

In our environment we have 2 DCs. One suddenly stopped working so I had to image and promote a new DC. I've set up DNS on the new server, and did some cleanup in the DNS manager erasing the old DNS records. I've tried flushing and registering the DNS.

After reading several forum posts, I'm still unable to address the issue. Any advice would be appreciated.

    Hello，

    It sounds like your computer may still be pointing to the old DNS server as its primary DNS server. To resolve this issue, you can try the following steps:

    1. Open the network adapter settings on the affected computer.
    2. Under the TCP/IP properties, make sure that the new DNS server is listed as the primary DNS server.
    3. If the old DNS server is still listed, remove it from the list.
    4. Run the command "ipconfig /flushdns" to clear the DNS cache on the computer.
    5. Run the command "ipconfig /registerdns" to register the computer's DNS records with the new DNS server.

    After completing these steps, try running nslookup again to see if it is now querying the correct DNS server.

    Let me know if this helps!

    Best regards
