We have a service desk license with 2 Agents and one administrator.
Administrator do not have the Agent access.
Now As a administrator, If i try to access and update service desk setting I am getting the following message.
Snap! You can't view this page
You need to be a Service Desk Agent to access this page. Contact your administrator if you need access.
But, i do not have rights to enable service desk agent access to myself 
Can any one help.
