Is it possible to reload a single Domain without restarting the Active Roles service?
If a large number of Active Directory Domains are managed by Active Roles, restarting the Active Roles service may take a long time. If a Domain goes offline for any reason, is it possible to re-establish communications without restarting the Active Roles service?
In some circumstances, it may be possible. The following steps are safe to try, but if they are unsuccessful, it will be necessary to restart the Active Roles service in order to re-establish communication.
In the Active Roles Console, navigate to Configuration | Server Configuration | Managed Domains
Find the Domain which is experiencing issues. Right-click on it and choose All Tasks | Advanced Properties
Find the edsvaLoadDomainInformation boolean attribute.
