We have an Active Directory DNS domain bac.amsted. We also have a LINUX DNS domain of baltimoreaircoil.be. We want to add/update the Active Directory DNS with the entries found in the LINUX DNS. We have tried to setup the baltimoreaircoil.be domain as a Secondary in AD with the LINUX being Primary. If we Click "Reload from the Master" the LINUX domain records appear. After 7 days they disappear due to the Scavenger process. The LINUX records only refresh when we manually perform the reload. What do we need to do to make these records automatically refresh?
