I currently waste a lot of time making dns changes for my organization. DDNS of course helps for workstations, but we still have a few thousand unique servers with still more applications needing cname records that DHCP/DDNS alone will not support, so someone needs to make updates, but I'd like to see sysadmins make their own dns updates for their machines. I'm currently working on extending our asset database to support this functionality, but I hold out hope that there are COTS solutions available.
