The following SCCM collection query can be used to list all computers which haven’t been seen by Active Directory for more than 90 days.
Please note: This collection query requires the Heartbeat Discovery method to be enabled.
To use you will need to create a new collection and add as a Membership Query Rule.
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 where SMS_R_System.Name in (select Name from SMS_R_System where ((DATEDIFF(day, SMS_R_SYSTEM.AgentTime, getdate()) >=90) and AgentName = "SMS_AD_SYSTEM_DISCOVERY_AGENT")) and SMS_R_System.Name in (select Name from SMS_R_System where ((DATEDIFF(day, SMS_R_SYSTEM.AgentTime, getdate()) >=90) and AgentName = "Heartbeat Discovery"))
