Hi all,
We're having a bit of a problem here. We have a domain here, domain.local, that has approximately 260 Windows Machines (XP, Win7, various MS Servers) and we also have users that bring in iOS devices, Kindles, Androids and so-forth. The domain controller runs dhcp, dns, wsus, and is a file server. We only have a single dhcp server and a single dns server on a Windows Server 2008 R2 box.
We have a wireless network by Aruba that has three SSID's on it. One is secure, two are firewalled and open. You can ping the chromebooks on either of the wireless networks. the DHCP server works find on all of these.
We started off getting bad_address entries from the chromebooks when they went on our network back in September. Creating a dhcp lease solved most but not all. We are still getting dozens of entries in the dhcp log that specify bad_address. We have the dhcp
server testing twice before issuing. Once in a great, great while, we might get something on an Android, but that is it.
Funny thing is, Chromebooks are being handed IPs (horray) and we can see the leases in the dhcp server. Well that really isnt funny, but what is, dynamic updates to dns are not happening. They exist nowhere in the forward zone or as a reverse pointer.
Kindles, iOS machines, Androids, Windows machines and everything else work flawlessly.
So two things... bad_address in the dhcp area and the dhcp dynamic updates are not happening for the Chromebooks.
Dns is set to "Always dynamically update DNS A and PTR records.
Discard A & PTR records when lease is deleted is checked.
Dynamically update DNS A and PTR records for DHCP clients that do not request updates is also checked.
Name protection is turned off as of today.
Any Ideas?
Thanks!
Steve
