Install prerequisite hardware and software

On hardware that meets system requirements, install the following:

• On the Persistent Chat Server Front End Servers:

• An operating system that meets system requirements

• Software prerequisites for computers running Lync Server 2013

• SQL Server on the server that will host Persistent Chat Server database

If Persistent Chat Server compliance is required:

• SQL Server on the server that will host Persistent Chat Server compliance database

Any user who is a member of the local Administrators group.

Determining your system requirements

Technical Requirements for Persistent Chat Server

Create the appropriate internal topology to support Persistent Chat Server (and optionally, Persistent Chat compliance)

Run Topology Builder to add a Persistent Chat Server pool to your topology:

• Add Persistent Chat Server components to the topology

• Create a SQL Server database for the Persistent Chat Server store (and a backup SQL Server for disaster recovery)

• Define a new Lync File Store or use an existing Lync File Store for Persistent Chat Server files

• Associate the Lync Server 2013 pool that can route requests to this Persistent Chat Server pool

If Persistent Chat compliance is required:

• Add Persistent Chat Compliance Store

• Click the Persistent Chat Server pool definition check box for enabling compliance

• Publish the topology

If you install Persistent Chat Server on Standard Edition, the fully qualified domain name (FQDN) of the Persistent Chat Server pool must match the Standard Edition server, and the SQL Server databases are collocated on the SQL Server Express instance on the Standard Edition server

To define a topology, an account that is a member of the local Users group.

To publish the topology, an account that is a member of the Domain Admins group and RTCUniversalServerAdmins group, and the user should also have full control permissions (read/write/modify) on the Lync File Store for Persistent Chat Server files (so that Topology Builder can configure the required DACLs).

Adding Persistent Chat Server to Your Deployment in the Deployment documentation

Deploy Persistent Chat Server

Run the Lync Server setup on all the computers running Persistent Chat Server. The Persistent Chat Server setup is integrated into the Lync Server 2013 Deployment wizard that provides the following instructions:

• Deploy local management store

• Install Persistent Chat Server services

• Request and assign certificates

• Run and start the services

Any user who is a member of the local Administrators group.

Deploying Persistent Chat Server in the Deployment documentation

Create a Persistent Chat administrator

Add users to the CsPersistentChatAdministrator security group.

Any user who is a member of domain administrators.

Adding a Persistent Chat Administrator in the Deployment documentation

Configure Persistent Chat Server

Configure users:

• User has to be enabled by policy to access Persistent Chat Server. By default, the policy is turned off for all users and can be defined at global/site/pool/user scopes.

• Configure settings

User must be a member of CsPersistentChatAdministrator. To change policy, user must be in CsUserAdministrator, at a minimum.
