Lync Enterprise and Lync Hosted

Jun 05, 2015
Updated: 2014-08-29

The Lync Enterprise and Lync Hosted services for Services Manager deliver unified communication services from the cloud. Installing the Lync web services creates a web site on the Lync Front-End server. Both the Services Manager Web server and Provisioning server issue commands on the Lync Front-End Server using a web service.

The Lync Enterprise service brings basic multi-tenancy to environments using Microsoft Lync Enterprise 2010 or 2013. The Lync Hosted service is deployed in environments using Lync Server 2010 or 2013 Multitenant Pack for Hosting, which provides full isolation of customers.

Supported versions

The Lync Enterprise and Lync Hosted services support the following versions of Lync Server:
Service Name Lync Server Version
Lync Enterprise (2010) Lync Server 2010
Lync 2010 for Hosted Lync Server 2010 Multitenant Hosting Pack
Lync Enterprise 2013 Lync Server 2013
Lync Hosted 2013 Lync Server 2013 Multitenant Hosting Pack

Lync server requirements

When configuring the servers that will run the Lync Enterprise or Lync Hosted web services, ensure the following requirements are met:
Requirement Lync Server 2010 Lync Server 2013
Install .NET Framework (Full) Version 4.0 Version 4.5 (64-bit)
Install Lync Server Management Shell Yes Yes
Enable IIS 6.0 (minimum) Yes Yes
Enable Remote Server Administration Tools > Role Administration Tools > AD DS and AD LDS Tools Yes Yes
Enable PowerShell Version 2.0 Version 3.0

Certificate and DNS requirements

When preparing your Lync deployment for provisioning to customers, ensure the domain for the customer you are provisioning is included on the certificates that exist on the Lync Front-End and Director servers.

For provisioning the DNS records required for the Lync services, configure the DNS service. This enables Services Manager to provision the customer's forward lookup zone, as well as create the Host (A) record for SIP, and create the SRV records required when you provision the Lync service. You can define the Lync DNS records that Services Manager will create when you configure the Lync service settings. For more information about configuring the DNS service, see Deploy the DNS service.

If the DNS service is not configured, you will need to create the following DNS records manually for each customer:
  • A forward lookup zone for the domain to which you are provisioning the customer.
  • SRV records, _sipinternal and _sipinternaltls
  • Host (A) record for SIP, specifying the Lync Director server's IP address

Deployment overview

Typically, deploying the Lync services includes the following steps:
  1. For Lync 2013, deploy the Distributor Report fix according to the instructions in CTX139274, in the Citrix Knowledge Center.
  2. Install the web service on the Lync Front-End server.
  3. Configure the Lync service using the control panel.
  4. If you intend for Services Manager to provision DNS records for the Edge and Front-End servers in your deployment, configure the DNS service.
  5. Provision the service to customers.

Changes to the server during installation
