Our Exchange server lately will not install the downloaded updates. There seem to be 30 important updates that it can not install, but any new ones other than these 30 seem to install just fine. I have tried rebooting the server and trying again, tried rebuilding the "C:\Windows\SoftwareDistribution", running the system update readiness tool, and installing one update at a time from Windows Update and by each KB # on Microsoft site. None of these steps has worked so far. Every time I try, an error code 800F082F and 80070643 is returned.
We are running Microsoft Exchange 2010 v4 on a Windows Server 2008 R2 virtual machine.
Any suggestions?
