Dns updating software
Our DHCP was set to lease addresses for 1 day, for reasons which were never explained to me.
I set this back to 7 days, in an attempt to give DNS a chance to 'catch up' before the addresses potentially changed again, but we're still getting incorrect DNS entries. Our settings are now an amalgam of what went before (which didn't work) and what I've gleaned from MS documentation.
When I joined the company, I noted that a lot of name lookups were failing or pointing at the wrong machines.
This might be an issue, maybe someone with more knowledge can elaborate.In the Advanced TCP/IP settings of each clients network adapter, is "Register this connection's addresses in DNS" checked? I've picked two records that are out of date - the owner is SYSTEM.Neither of these had the service account in the permissions list.At the same time, I'm combing through AD and rationalizing group memberships.The Dns Update Proxy group, despite its description, had a domain admin account and the BES Service Account as members.
