1. In the Installed Services page, click Next.

2. On the Group Chat Database page, perform the following steps:

   Note:
   The Microsoft Lync 2010 Group Chat database cannot be located on the Group Chat Server.

   • In Server\Instance, specify the fully qualified domain name (FQDN) and instance of the server on which the Microsoft SQL Server database was created for Lync Server 2010, Group Chat (for example, groupchat.contoso.com\sqlserver2005).
     
     
   • In Database, specify the name of the database (for example, groupchatdb).
     
     

3. Click Next.

4. On the Database Settings page, errors are listed (if any) as the databases are examined.

   Note:
   There might be a slight delay while the databases are examined.

5. Click Next.

6. On the Super User page, specify one or more super users−users that have administrator rights and permissions on the Group Chat Server after they sign in to Microsoft Lync Server 2010, Group Chat Admin Tool.

   Note:

   The super users specified here will be the initial super users for this installation. You can add more super users later using Group Chat Admin Tool. The user name of the installer automatically appears in the Find and Add a Super User box. To add this user name to the Super User page, click Add. To add a different user to the Super User(s) page, specify a SIP Uniform Resource Identifier (URI) or user name, and then click Add.

7. Click Next.

8. On the Lync Server page, perform the following steps:

   Note:
   If you are installing an additional instance of Group Chat Server to create a pooled environment, the established settings from the server pool are used, and the Lync Server page does not appear.

   • In Host, specify the FQDN of the computer running Microsoft Lync Server 2010. In Microsoft Lync Server 2010, Standard Edition, this is the FQDN of the Front End Server. For Microsoft Lync Server 2010, Enterprise Edition, use the pool server.
     
     
   • In the Port box, select the Auto detect port check box, or specify the port used by the computer running Lync Server 2010 for mutual TLS (MTLS) connections.
     
     
   • Under MTLS Certificate, click Browse to select the location of the certificate. Your computer may have several certificates installed. Make sure you select the certificate that has the specific purpose of server authentication.
     
     

9. Click Next.

10. On the Lookup Service page, perform the following steps:

    Note:
    If you are installing a second or third instance of Group Chat Server to create a pooled environment, the established settings from the server pool are used, and the Lookup Service page does not appear.

    • Under Lync Server 2010 credentials, type the Lookup service account you created prior to installation. In the SIP URI box, specify the SIP URI of the Lookup service account. SIP URIs are not case-sensitive.
      
      
    • In the Username box, specify the name of the Lookup service account. This can be in the following formats: username@<domain> or <domain>\username.
      
      
    • In the Password and Confirm Password boxes, type the password for the account.
      
      
    • Under Settings Specific to this Machine, in the Pool Communication Port box, specify the internal server communications port to be used to listen to messages from other servers in the system’s server pool (that is, to allow all servers to communicate with each other and share data, such as chat history and channel settings, with all other servers in the system). The default port for the Lookup service is 8010.
      
      

      Note:
      The pool communication port for the Lookup and Channel services installed on the computer must use different ports. For example, if the pool communication port for a Lookup service is 8011, the pool communication port for the Channel service on the computer cannot be 8011.

11. Click Next.

12. On the Channel Service page, perform the following steps:

    • In the Username box, specify the name of the Channel service account. This can be in the following formats: username@<domain> or <domain>\username (this is the Channel service account you created before installation).
      
      
    • In the Password and Confirm Password boxes, type the password for the account.
      
      
    • If the Application Pool Name box is empty, you can specify an application pool name. This is an FQDN and must match the subject name for the certificate that was previously assigned. This can be the computer name or a pool name if you want to use the same application pool name for multiple channel servers. However, if you use the computer name, you cannot assign another application to the application pool. This scenario applies if you have installed a second Group Chat Server and want to use the same application pool name and certificate.
      
      
    • If the Site Name box is empty, open the Lync Server Management Shell, and run the Get-CSSite cmdlet to get the site name.
      
      
    • In Pool Communication Port, specify the internal server communications port to be used to listen to messages from other servers in the system’s server pool (that is, to allow all servers to communicate with each other and share data, such as chat history and channel settings, with all other servers in the system). The default port for Channel service is 8011. This setting cannot be the same port used by the Lookup service on the computer.
      
      
    • In Service Listening Port, specify the port to be used to listen for inbound client connections. The default value for this port is 5041. The installer will create a trusted application pool, trusted application computer, and trusted application for the Channel service by using this port.
      
      

13. Click Next.

14. On the Compliance Settings page, perform the following steps:

    Note:
    If you are installing a second or third instance of Group Chat Server to create a pooled environment, the established settings from the server pool are used, and the Compliance Settings page does not appear.

    • To start compliance logging when the system is installed, under General, select the Turn on Compliance Server Logging check box.
      
      
    • In Compliance File Repository, browse to and select a network share to store a copy of any uploaded files. The Compliance service account must have read and write access to this directory.
      
      

15. Click Next.

16. On the Web Services page, specify the directory that you want to use to store files that are uploaded to the Web service.

    Note:
    If you have deployed multiple Group Chat Servers, this must be a shared network directory. The directory must be separate from the Web Service page, and the Channel service account must have read and write access to the directory.

17. Click Next.

18. On the Installation Summary page, click Finish.

After the Server Configuration wizard closes, the Group Chat Server Setup wizard displays the Installation Complete page.
