Hello, I am attempting to perform windows update on Server 2008 SP2 (not R2) and get an error 0x80070490. After some digging around I found this article (http://support.microsoft.com/kb/958044/en-us) that said to perform a repair install of Windows. However when I follow the steps outlined in the article the option to perform an "Upgrade" is not availalbe, it says that you need to use a later version of windows to upgrade. This is the same media I originally installed from, and the only media for Windows Server I have. How can I go about performing a "Repair Installation" of Windows Server 2008? Thanks, Cameron

Did you click Go online to obtain the latest updates for installation (recommended) .?

Hi, Thanks for the post. From your description, I understand that the error code 0x80070490 is received when performing Windows Update on Windows Server 2008 SP2; however, the system indicates that a later version of windows is required to upgrade when following the repair installation steps mentioned in KB958044. Please understand that your current system version is Windows Server 2008 SP2. If you try to insert the Windows Server 2008 installation DVD to perform upgrade procedure, the system will say that a later version of windows is required. We need to insert Windows Server 2008 embedded with SP2 DVD. If you have any installation media-related issue, it’s suggested to contact Microsoft Customer Support Services (CSS) so that a dedicated Support Professional can assist with this request.

And there have been no event 471 in the event log. So how are people that have upgraded to SP2 supposed to perform the steps outlined in the knowledge base article? I never received a disc with SP2 slipstreamed, in fact it downloaded via windows update. Thanks, Cameron

Miles Hi Miles, I've run this tool a few times now, without any success really. I've e-mailed the log files to you, but they do not list any missing or corrupt files. see below for the CheckSUR.log contents - ================================= Checking System Update Readiness. Binary Version 6.0.6002.22202 Package Version 6.0 2009-12-29 10:27 Checking Windows Servicing Packages Checking Package Manifests and Catalogs Checking Package Watchlist Checking Component Watchlist Checking Packages Checking Component Store Summary: Seconds executed: 120 No errors detected As it appears that I cannot perform a repair install with SP2 applied, should I be looking into uninstalling SP2? The link you provided does not contain any helpful information on obtaining a CD with SP2 already applied, it only asks for information on the support plan I have purchased.

Hi,Thanks for the update.Yes, you could perform a repair install after uninstalling SP2 if possible. In this way, the corrupt system files should be replaced correctly.Thanks,Miles

Hi, Thanks for the update. Yes, you could perform a repair install after uninstalling SP2 if possible. In this way, the corrupt system files should be replaced correctly. Thanks, Miles Thanks Miles, So the questions would be then, how do I go about uninstalling SP2? It does not appear in the Programs and Features list, although lots of other windows updates do. I've been attempting to find some documentation on how to un-nstall it manually, but it does not appear to exist. Thanks, Cameron
