Hey experts. Ok so we have a 2008 sbs.<br />
There are a handful of websites we go too often that occasionally tell us they are unavailable. If I clear out the Server dns cache the sites come back and are just fine. <br />
Any ideas why this is happening and how I can fix this?<br />
<br />
THankS!

Sites un accessable until I clear the Server DNS cache

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.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.
