Problem: 
It was detected that the Svr-Claret server was not recognizing the names in its network, so it was not accessing the DNS.
 
Solution:
1. After performing the test, we saw that the server had as DNS the standard which is reddog.microsoft.com
2. Once this was detected the DNS name was modified by the domain name "claret.local" this is in the route:
/etc/resolv.conf
3. by doing that you already had communication with the DNS (vm-dc-prod-12)
