Review the "Domain" field in the event description to identify the failed domain.
Verify that the domain has the "Available for management" status in the Active Roles console. If not, make sure that at least one domain controller for that domain can be contacted from the computer running the Administration Service.
Once you have performed the above checks, update the membership of the dynamic group by clicking "Rebuild" on the "Members" tab in the "Properties" dialog box for that group, in the Active Roles console.
Alternatively, you might update the membership of all dynamic groups by using the Active Roles console to execute the "Dynamic Group Updater" task located in the "Configuration/Server Configuration/Scheduled Tasks/Builtin" container.
