Just an FYI that if you ran into an issue starting back in June where you see the Windows Server 2003 Standard Edition x86 Service Pack 2 (SP2) installation as an option when you scan the machine at the online Microsoft Updates website but cannot select the package in the ITMU Distribute Software Updates Wizard (DSUW) in SMS then we have a fix for you.  A property of SP2 was changed in the June 2007 and July 2007 versions of the Security Updates catalog file and as a result of this change you may see the symptom noted above.   So what's the fix?  Just use the August version of the Security Updates catalog file where the previous change is undone.  I hope this didn't cause you folks too many headaches and helps solve the mystery.
