Excellent, thank you!

Microsoft should hang their heads in shame and make this information EASILY AVAILABLE themselves!

It would also helpful if @@VERSION returned a unique software level. We became really confused after applying the original SP2, then the first GDR. We used the re-released SP2 on subsequent builds (which included the GDR changes) and found that @@VERSION (i.e. sqlserver.exe) was different between the builds. It didn't even match that expected in KB 933508. They amended the KB later.

GET THE BASICS RIGHT MICROSOFT!!!!
