Looking in  the server 2012 DNS manager, The list of computernames  do not have updated ip addresses:  meaning the ip address are no longer valid.  How can I refresh this information.

Thank you

Do your computers use static IP addresses or dynamic? If you right click on your domain you can select reload--is this DNS a primary or secondary DNS?

Primary DNS........Workstations set to DHCP (sonicwall)


Ok I got the DNS to refresh correctly after making changes to the Properties general tab "Dynamic updates".

My nod32 console is pulling the information from Active directory. The list is not updating to the correct list now shown in dns manager.

If you have made a lot of changes lately or your DNS leases are set to expire very frequently this list may have to be constantly reloaded. Can you give me some idea as to how you have this setup--how long are your DHCP leases? Lots of recent changes?

Server is only about 3-4 months old.   As for the DHCP leases...what ever is standard in the firewall.  

I cannot find in the AD a computer list that includes the ip addresses,  Under computers just the names.  Very frustrating to have the DNS and the AD computer list reporting different ip addresses.......I reloaded the DNA list as suggested...worked great.  The server is out at a customer site.

I'm confused now. In your last post you said you CAN'T find a list in AD with IP addresses but then you go on to say they have different IP addresses. I too do not know of anywhere to find AD listings of computers that also include their IP addresses.

Sorry, let me explain. Your right: DNS computer list is correct with IP addresses. In Ad I have not found a computer list that shows IP addresses.  

Eset Nod32 console scans the AD (per eset ) to populate a list of computers (with IP addresses) and lists those computers with the computer name and associated IP address.  This list is wrong and I can only assume Eset is pulling the names and IP addresses (somehow) from the AD. I guess this is the "real" question at this point.

Question: does the Ad store a list of computer names with associated IP addresses?

I hope I was clear..

OK I'm fairly confident in saying that D does not store IP addresses. I have also looked at several sites I rely on for info and had this verified. According to these readings your system event logs gathers IP addresses at logon but does not store them in AD. As such I would look into ESET and ask them where they are getting the IP addresses and if they are auto updated every so often or if once gathered never changes. Unfortunately I don't know ESET, I use AVG, and it get the IP address when the PC is "new" to it. I recently changed a IP address (I use static) from .96 to .196 and the PC still says .96 in AVG. I will change it back to .96 in a few days but if I want it to update to .196 I have to remove the PC from the list and then when it logs back in it will get the updated IP address. Sorry I can't give you more specific ESET info but maybe its similar to AVG, hopefully.
