Last night, I moved the DHCP role to a second domain controller, and then demoted the one I moved it off of (had to be force removed because of some errors).
This morning, about half of the DNS A records of the computers in that office showed up in DNS (timestamp at 6 AM, when they automatically booted). But half of them have no DNS records. Why are some of them not showing up?
The only unusual event viewer warning is that it didn't have DNS credentials. http://support.microsoft.com/kb/282001/en-us I put those in like the website said, and still nothing.
In IPV4 & scope Properties > DNS tab, I changed the option to Always dynamically update DNS. No good.
Why is this half working? What else can I try?
