Managed metadata service not working

Problem:

The Managed Metadata Service or Connection is currently not available. The Application Pool or Managed Metadata Web Service may not have been started. Please Contact your Administrator

Solution:

After googling for many hours, I was able to fix this problem. Here is the check list to fix it properly.

1.Make sure managed metadata service application pool is started in IIS
2.Make sure managed metadata service aplication pool identity has full access on service's physical folder
3.Go to central admin > Service applications > select managed metadata srevice and click on administrators. Add local farm and system account users to this list
4.Go to central admin > Service applications > select managed metadata service and lcick on permissions, add local farm and system account and allow full control for this
5.reset IIS


Note: Please note that we are trouble shooting this on a developer machine and giving local farm and system administrator account full access doesn't cause any problem, please use appropriate accounts for the same.

Happy administration
