I am consistantly getting 4515 and 409 errors logged on my SBS Server. There is only one DNS Server in the topology and two domain controllers. I used to have the other dc as a DNS Server as well but the consultants couldn't get it figured out so the service was deleted. The errors appear every few days or so.<br />

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
