End of Life Products and Features - Deploying a Second Express for Lync Appliance within the same Organization
Overview
In most organizations, most organizations are geographically separated, which requires critical servers in all locations. Microsoft Lync, being a pure unified communication tool within the organization, needs to be accessible throughout the organization. It can be configured in many different ways, but this document will focus on deploying a second Standard Edition Front End Server, and deploying the Pool Pairing features to provide failover functionality to the organization.
For more information about pool pairing, please go to http://technet.microsoft.com/en-us/library/jj205293.aspx
The diagram being used as a reference to this guide is below:
The primary unit in this scenario is fully deployed. This guide will show you how to add the second unit to the main topology on the primary appliance. Once done, all other roles can be added the same way that was done for the primary device.
Add the Second Express for Lync Appliance to the Existing Domain
To add the Express for Lync appliance to your Active Directory Domain Infrastructure, please follow the steps below:
On the Windows Start Screen, right click on "Computer" and select "Properties".
This will bring up the "System" window. In the Computer name, domain and workgroup settings, click on the "Change Settings" link.
In the "System Properties" window, under the "Computer Name" tab, click on the "Change..." button.
In the Computer Name/Domain Changes window, select "Domain:" from the "Member of" section. In the textbox below "Domain:", enter the AD Domain name. In this example, i will be using the domain lynctest.local. Click OK to accept the changes.
Windows Security will ask you to enter a username and password associated with a Domain Administrator account. If you have left the Express for Lync domain credentials at defaults, use the following credentials:
Username: administrator
Password: sangoma1!
If you have changed them, please use the valid Domain Administrator account and click OK.Once the changes are accepted, the Computer/Domain window will welcome you to the new domain. Click OK to proceed. It will then inform you that the appliance will need to be restarted to complete the process. Click OK to restart the appliance.
Once restarted, you would need to login with the new Domain Credentials. if you use the old credentials, you will not log into the domain and will not be able to complete the Lync Server setup.
At the windows welcome screen, select "login as different user", and under the username use the notation "DOMAIN\USERNAME". Enter the password below it
Deploy a Second Standard Edition Server
The deployment of a second server is slightly different then deploying the first front end server. Not all of the steps within the deployment wizard need to be run as they have already been done for the domain. Before you begin, you must first add the second server to the topology on the main appliance.
Add the Second Server to the Main Lync Topology
Follow the steps below to add the second appliance to the main Lync Topology.
