MMC cannot open the file C:\Documents and Settings\All Users\ Application Data\Microsoft\ SmallBusinessServer\Administration\ itprosbsconsole.msc.
This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC.
This may also be because you do not have sufficient access rights to the file.
When you reapply SP2 this error may occur. You will need to update the MMC console to the newest version.
