<div class="content wysiwyg-content">
I have a lync 2013 fe server running correctly internally on domain xserver10.local with other domains Xserver10.com, and xserverb.com. &nbsp;<br />
<br />
I have the edge server built and running but it appears that the split brain DNS is the issue connecting externally. &nbsp;What entries do I need to make for xserverb.com and xserver10.com to allow it to connect to .local domain?

Split Brain DNS

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.
