This error just showed itself on my Windows 2008 R2 SP1 server and it stopped me from installing any updates. The fix for this error is undoubtedly the strangest I ever came across. Pete Long described this fix on his website.
Strangely enough this error seems to be caused by the taskbar that is not showing all icons. Here are the steps:
- Right-click the taskbar and select properties
- In the Taskbar tab click Customize…
- Check "Always show all icons and notifications on the taskbar"
- Confirm all screens with OK
Now try installing the updates again and see that it'll work.
Recently I did an update run on my SharePoint 2010 farm and I fixed some errors that were showing in the event log. This resulted in one specific error that resulted in an Access Denied on one of the sub-sites. The permissions weren't changed and even the Site Collection Administrator account was denied access. Here's what the solution was.
One of the errors that I tried to fix was setting the portal super reader account for proper caching. Unfortunately I didn't take the time to actually read up on it and I just entered an account that "should" work.
This resulted in an error in ULS about the Navigation not being able to be properly accessed. This was directly related to the access denied error. Seems like setting the account wasn't such a good idea. So I reset the property which instantly fixed the problem.
