I got a question from our SMS admin today on why some reports were not working properly. They were only returning a very small number of records when there should have been a LOT more. After some digging, I was able to determine that some custom MOF changes that had been made by the previous SMS admins (those punks!) had been overwritten when SMS 2003 SP2 was installed. So, we haven't been capturing any of this data for the last 7 months or so. Thankfully,
Mr. Tucker is a sharp guy and has a backup of the custom MOF that was in use before (I think he got bit once when an upgrade and/or site reset overwrote the custom MOF and learned his lesson). So, we'll just have to identify the differences and create a new customized MOF. Then, I guess you have to push out MOFCOMP to all of your existing Advanced clients so they load the custom class into the WMI namespace. I don't think it will end up being that big of a deal but no one here (including me) has been through the process before. I asked the SMS admin to do some research to make sure we don't miss anything obvious. Should be fun!
