If you need to get the machines referenced by GUID from a particular status message, use this SQL Query.
Select distinct Name0
from [SMS_TLA].[dbo].[StatusMessages] as stat
left outer join [SMS_TLA].dbo.StatusMessageAttributes as att on stat.recordid = att.recordid
left outer join [SMS_TLA].dbo.StatusMessageInsStrs as ins on stat.recordid = ins.recordid
left outer join [SMS_TLA].dbo.v_StatusMessage as VStat on stat.recordid = VStat.recordid
inner join [SMS_TLA].dbo.v_R_System as SD on ins.InsStrValue = SD.SMS_Unique_Identifier0
join [SMS_TLA].dbo.ClientKeyData as CD on SD.SMS_Unique_Identifier0 = CD.smsID
join [SMS_TLA].dbo.v_RA_System_SMSAssignedSites as SAS on SD.ResourceID = SAS.ResourceID
WHERE (VStat.MessageId = '5447') AND
(stat.ModuleName='SMS Server ') AND
(ins.InsStrValue like 'GUID:%') AND
DATEADD(dd, 0, DATEDIFF(dd, 0, stat.Time)) >= '2013-10-17'
--DONT FORGET TO UPDATE THE DATE!
order by Name0 Desc
Please don’t forget to change the SMS_TLA from three letter acronym to the appropriate database name in SCCM!
