I keep coming across this in the MS Press Training book for MCTS 70-236 \nExchange 2007 Configuration, and it's bugging me. The author(s) keeps saying \nthat you must reapply a service pack after adding Windows components such as \nIIS, networking services, etc. in Server 2003, unless you used slipstreamed \nmedia to install of course. I have always thought that was only back in the \nNT4 days? Through my travels/learning and talking with other people I thought \nthis annoyance was solved in Windows 2000 and newer, so quite a long time \nago. Is it true, or dependent on how you installed the SP? Generally I \ninstall the OS, then use a network install file to apply the SP, deleting it \nafter I'm done since I assume it's no longer needed.\n\nIf it's true it worries me that I've been doing it wrong for so long, and if \nit's not true it really worries me that an official MS book would be printing \nthis. I have been doing some web searches but I see no other mention of \nreapplying service packs past NT4 anywhere. In fact I found a MS KB saying \notherwise even for Win2000 at [URL]http://support.microsoft.com/kb/274215[/URL]. But I'm \nnot sure that clarifies it either... Say I install Server 2003, then use the \nSP2 file to apply the SP. If I install IIS afterwards and it asks me for the \ndisc, I'll put in the original disc (or point it at i386 copied from the \noriginal disc), and assume it grabs any updated cabs from the SP it needs \nfrom the driver cache folder as well. Is this not correct?
