This is a neat trick that Matt showed me today.
I installed a based build OS with Windows 2003 R2 and SP2 on it. Then started my exchange install and forgot about IIS.
So I go an install IIS and it asked for the SP2 disk. Damm, where did I put that.
Matt showed me that I didn’t need the SP2 disk as the files are already on the OS in C:WINDOWSServicePackFilesi386
Every day IS a school day!
