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: http://sharepointologic.blogspot.se/2014/02/managed-metadata-service-not-working.html
