Fix broken Managed metadata service and more after CU update

After installing the September CU for SharePoint 2013 Server I have several problems.

The two most annoying things:

  • The Managed Metadata Service went down, giving me no managed navigation and no access to term store.
  • The User Profile Synchronization Service stopped and refused to start.

After trying numerous things (including recreation of the Managed Metadata Service application…) I found this message in the ULS logs:

w3wp.exe (0x1D78) 0x21A0 SharePoint Server Taxonomy ca3r Monitorable Error encountered in background cache check System.Security.SecurityException: Requested registry access is not allowed.     at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable)

Googling this error gave me some input! There is a command in psconfig.exe with the purpose of setting correct permissions on SharePoint registry keys.


psconfig -cmd secureresources

resolved all my issues.

Here is the blog post that guided me to the correct solution:
