A flute without holes, is not a flute. A donut without a hole, is a danish.
I'm setting up my SQL Server 2000 course for this week. 12 machines, twelve copies of SP3 that need to be installed. I'm sure this could be done in some sort of automated fashion, but I've never learned all those methods because AutoIt has been so good to me. Just throw SP3 on a network share, and run the script from all the machines. Pretty painless.
