Resolução
When handling a DMZ RODC setup you must do one of the following as RODC's will not be returned in the standard DNS lookups for the domain:1. Join to the specific RODCs servers.# /opt/quest/bin/vastool -u <admin> join yourdomain.com rodc1.yourdomain.com rodc2.yourdomain.com2) Join including the AD site name that the RODCs belong to# /opt/quest/bin/vastool -u <admin> join -s RODC-SITE yourdomain.com3) Modify the RODCs to register in the global DNS zone, so they are returned during a normal query. Please reference Microsoft materials or contact them for help with this procedure.
