Is there a way I could remove computers not found in AD from a collection membership?
Using this to grab all systems
select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System inner join SMS_G_System_SYSTEM on SMS_G_System_SYSTEM.ResourceID = SMS_R_System.ResourceId where SMS_G_System_SYSTEM.SystemRole = "Workstation")
