Dhcp not updating a records in dns
Discard A and PTR records when lease is deleted Dynamically update for DHCP clients that do not request updates As far as my understanding goes (which is clearly not far enough), DHCP should update DNS as soon as it itself updates.Our DHCP was set to lease addresses for 1 day, for reasons which were never explained to me.The DHCP service needs some valid way to tell the DNS server to update the records.Although really the hosts should (for the most part) be doing this on their own with out help from the DHCP server at all.The Dns Update Proxy group, despite its description, had a domain admin account and the BES Service Account as members.I did a bit of reading and discovered that the group should have DNS computer accounts in, if the zones are configured to only be updated securely - which they were. I am forever getting incorrect / outdated lookups when connecting to machines.Dont have a router there, only a 3750 tied in via a fiber link.
Scavenging appeared to be configured, but not actually working.
Would appreciate any pointers on getting this to work.
When I joined the company, I noted that a lot of name lookups were failing or pointing at the wrong machines.
I mentioned this and got 'Yeah, we know.'So I decided to do some poking around.
At the same time, I'm combing through AD and rationalizing group memberships.
