Since the update I've noticed that the managed metadata service is not working correctly anymore. The Term Store can be accessed via central admin, but not from site settings.

I've reset IIS, and set read permissions for the app pool service account (althought this was not set before, no issues had occurred). Still have not been able to access term store.


Error encountered in background cache check System.Security.SecurityException: Requested registry access is not allowed.

  • did you check the ULS logs or event log for more details? what error u getting? one more thing, if you un associated the MMS proxy from the web app and then re associate it. then test again

  • Tried your suggestion and it did not resolve it. Also tried recreating an entirely new MMS and it did not work either.

open cmd as administrator


cd C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\BIN

then type:

psconfig.exe -cmd secureresources
