DNS network issue

On a Windows 2003 Active Directory network, we removed an extra DNS server and added a new one to replace it.  The client machines show the new DNS server when IPCONFIG /ALL is run but the servers are still showing the old backup DNS server and not the new one.  What is the quickest and easiest way to update the servers to point to the new DNS backup server?  Will IPCONFIG /FLUSHDNS and then IPCONFIG /RENEWDNS take care of this without bumping off the users on each server?  Any assitance offered would be greatly appreciated.

My guess is your PC's get DNS from DHCP while servers are manually updated via GUI.
Do you have so many servers that a script would come in nicely?

This is due to you must have changed it on your DHCP server.

Now all clients are picking up the new DNS server from DHCP, but servers use static IP address and does not take any config from DHCP server.

You need to change the DNS server IP address from network Card properties manually.

The new backup DNS server is also the new DHCP server.  I still see the old DNS server that no longer exists under DNS/Reverse lookup/Named Servers.  Should this be removed along with updating the network card properties manually for the servers?

Yes, you should remove the old entry from DNS database.

But, if you still have that server physically and have only removed DNS service from it, then you can leave the entry in the DNS database.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

The server has been completely removed from the network.

And no other server is running with its name.

If yes, then you can safely remove the entry from DNS.

Yes, no other server is running with its name and it is okay to remove from DNS/Reverse lookup/Named Servers, correct?
