Executive Summary:
| A healthy Microsoft Exchange Server environment requires healthy Domain Name System (DNS) operations. DNS server integrity is crucial to Microsoft Exchange Server operation—including DNS zone integrity, properly configured Active Directory (AD) components, and smooth name resolution. |
In “Troubleshooting DNS Problems in an Exchange Environment” (http://www.windowsitpro.com/Articles/ArticleID/95748/95748.html), I explained that the health of your DNS operations is crucial to the health of your Exchange environment. I covered two types of DNS problems that affect Exchange: connectivity between Exchange servers and DNS servers, and performance of DNS servers. In this article, I explain the importance of DNS server integrity, including zone integrity, Active Directory (AD) DNS, and name resolution. Note that before you can troubleshoot DNS, you must validate connectivity to your DNS service. . . .
