Depending on how your administrator has defined the roles you are assigned, it is possible for you to see potentially misleading information in certain applications or be unable to perform administrative tasks as you expect. For example, if you select a role with administrative privileges to access an application such as SQL Server Configuration Manager or Microsoft SQL Server Management Studio and connect to a remote SQL Server instances, it might appear as if you have permission to start and stop services or perform other tasks. However, if your role does not include network access rights for the remote SQL Server instance, you will not have the appropriate permission to perform those tasks.
You can check whether your selected role includes network access rights using the Authorization Center. If the role you are using does not include network access rights, you should click Advanced View to see if you have additional network roles available to use in conjunction with your local role. If the role you are using includes network access rights, you should contact your administrator to find out if those rights are applicable on the network computer you are attempting to manage.
