We just hardcoded the Fax server to point directly at a single server in the SMPT relay pool (10.x.x.x) versus the DNS pool name <br />
<br />
it worked but when we put the dns name of the HUB &nbsp;server smtp fails<br />
<br />
We saw that 1 DC was in hung state , how that can cause<br />
what could be the issue

EXCHANG , 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.
