Computers not seen in 60 Days

I found this post by Matthew Hudson over on his blog but it didn't seem to like the SMS_R_System.ResourceType bit of the SQL so I'm posting the SQL snippet I use.

It's a handy little bit to have for identifying those potential AWOL systems.

select SMS_R_System.ResourceId, 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_WORKSTATION_STATUS on SMS_G_System_WORKSTATION_STATUS.ResourceId = SMS_R_System.ResourceId where SMS_G_System_WORKSTATION_STATUS.LastHardwareScan >= DateAdd(dd,-60,GetDate())
