Windows Updates Fails Server 2008 0x80070490

I have a server with Windows Server 2008 Standard x64 Edition installed. This has been installed and running for several months and I have been able to successfully install previous Windows Updates. I have two pending updates that fail to install.

• (KB967723) Security update for Windows Server 2008 x64 Edition

• (KB976098) Update for Windows Server 2008 x64 Edition

Fails with Error code: 80070490

Followed this off Microsoft support site, which basically says to repair Windows with the install DVD. When I get to the step to select upgrade I get the following error.

Upgrade has been disabled. The upgrade cannot be started. To upgrade, cancel the installation and then choose to upgrade to a version of windows that is more recent then the version you are currently running.

So basically feel like I've hit a dead end with out doing a complete reinstall. Any ideas ?

I happened to be researching this same error code this morning, and came across this MSDN blog post that might help: How to overcome error 0x80070490 when installing updates in Windows Vista/Server 2008

I was not able to get it working again by following his step-by-step, but the following did:

1. Open %windir%\logs\cbs\cbs.log. You'll likely need to run Notepad as Administrator in order to view it.
2. Go to the bottom of the log and do a find for "Error", making sure you choose up for the direction

3. This should bring you to one or more errors like the following:

   2008-09-27 15:53:29, Error
   CBS Failed to resolve Package: Package_for_KB905866~31bf3856ad364e35~x86~~6.0.22.0. hr: 0x80070490

4. Do a web search for the KB number of the update that failed (KB905866 in this case), which should bring you to a Microsoft page where you can download the stand-alone installer for this issue's patch

5. Download and install the appropriate version (32-bit, 64-bit, etc.)
6. The next time you run Windows Update, it will recognize that the update was installed.
