> Has anyone installed SP2 successfully?
Yes, I installed BE SP2 and did not ran into any problems, it installed correctly the first time around. In my case it seemed to solve some of my problems although I am not sure, I was trying some other options at that time.
I do always make an image of the server of which I want to perform updates, BE or Windows for that matter, so if things go horribly wrong I can simply restore it.
