Need help in Installing the .NET framework in the proper order for Exchange Server 07

[albertwt]

To All Experts,

Can someone guide me in installing the .NET framework for Excahnge Server 2007 in my Windows Server 2003 x64 ?

I haven't applied this update yet:

Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x64
Date last published: 10/16/2009
Download size: 131.7 MB

too scared of things went wrong again ;-|
because since I regularly use Windows update it broke my Autodiscover and POP3.exe and IMAP4.exe also cannot be executed (failed to start).

but when I'm about to to download that 131 MB file above I couldn't find it, but instead MS Download website lead me to this:

Microsoft .NET Framework 3.5 Family Update for Windows XP x64, and Windows Server 2003 x64 (KB959209)
URL:

http://www.microsoft.com/downloads/details.aspx?familyid=A4F52459-DFE5-4BC3-8F7F-AA688879B1DC&displaylang=en#filelist

in which I shall install smaller file for the update:

1. Install the update for the .NET Framework 2.0 Service Pack 2 - NDP20SP2-KB958481-x64.exe
2. Install the update for the .NET Framework 3.0 Service Pack 2 - NDP30SP2-KB958483-x64.exe
3. Install the update for the .NET Framework 3.5 Service Pack 1 - NDP35SP1-KB958484-x64.exe

please let me know which one is the correct procedure to install it without breaking things apart in my production environment.

Thanks,

AWT

I'm confused why Windows Update website (Manual link Update) shows i need to install:
Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x64

rather than jumping directly into: Microsoft .NET Framework 3.5 Family Update for Windows XP x64, and Windows Server 2003 x64 (KB959209)

so far I don't bother to apply the .NET Fx update until I realized that my current error can be fixed by installing:
