Issue

Additional Windows Server roles and services are enabled on this server.

The Windows Server roles and services include AppFabric Hosting Services, Active Directory Certificate Services, Active Directory Domain Services, Active Directory Federation Services, Active Directory Lightweight Directory Services, Active Directory Rights Management Services, DHCP Server, DNS Server, Fax Server, File Services, Hyper-V, Network Policy and Access Services, Print and Document Services, Remote Desktop Services, Web Server (IIS), Windows Deployment Services, Windows Server Update Services.

Impact

For performance considerations, the AppFabric Caching Service should be configured on a dedicated server in a production environment.

Although there is no restriction against purposing existing servers, such as Web or application servers, as cache hosts on which the Caching Service is installed, the best performance and stability is achieved by using dedicated cache servers.

Resolution

Configure the Caching Service on a dedicated server.

To configure the Caching Service

  1. To install and configure the Caching Service, see Installing and Configuring Windows Server AppFabric (http://go.microsoft.com/fwlink/?LinkId=200331).
