Constant Problem with Microsoft .NET Framework 2.0

Every day I get a notice Windows update wants to install the same two
updates. Here is what runs when I allow then to run from Windows Update:

Initializing installation... done!
Installing Security Update for Microsoft .NET Framework, Version 2.0
(KB928365) (update 1 of 2)... failed!
Installing Security Update for Microsoft .NET Framework, Version 1.1 Service
Pack 1 (KB928366) (update 2 of 2)...

Updates not installed:
Security Update for Microsoft .NET Framework, Version 2.0 (KB928365)

I have downloaded and run dotnetfx.exe. Initially I ran the uninstall and
received an error it could not find the source. Then I rebooted and reran it
in repair mode and I get the same message.

I'm running Win XP Pro sp2 w/2 gig ram.
OS Name Microsoft Windows XP Professional
Version 5.1.2600 Service Pack 2 Build 2600

How do I resolve this problem?

Thanks,

Tony
