Do windows symbols files need to be exactly matched

I have windows xp that already up-to-date, and I have downloaded开发者_如何学JAVA Microsoft Symbols for Windows SP3. Can I use it with my XP? I don't have access to the original disc

Also I found original XP SP3 ISO here ftp://t1subnet-233-68.ideaone.net/ should I use that image instead?

Don't bother downloading the complete symbols pack. Just point WinDbg to MS symbols server, and it will download the appropriate symbols, when they are needed.
