Microsoft Lync Server 2010 Front End : Installation (part 2) - Enterprise Edition Installation

8/10/2011 6:28:43 PM

Enterprise Edition Installation

Lync Server Enterprise Edition is designed for larger deployments or those that require high availability or redundancy. Enterprise Edition enables you to have multiple front end servers in a pool, and it scales to support larger user counts with an outboard SQL database.

Topology Builder for Enterprise Edition Deployments

Lync Server uses the published topology to process traffic and maintain overall topology information. It is especially important to ensure all information included in the Topology Builder is correct because it sets the initial configuration information for deployed server roles. To ensure the topology is valid, it is recommended you run the Topology Builder before your initial deployment and publish an updated topology after each topological change. This example shows a Enterprise Edition topology. Remember, if you change the topology later, republish it to ensure consistency.

When you first launch Lync Server Topology Builder, you see a partially blank MMC screen, as shown in Figure 19. Compare this to the detailed result at the end of this example.

Figure 19. Topology Builder without a Defined Topology

To begin using Topology Builder, follow these steps:

On the right side of the Action pane, click New.

Define the default SIP domain. In many deployments, this is simply your domain name, as shown in Figure 20. In more complex deployments, additional SIP domains might be added by clicking the Add button. When you are done defining SIP domains, click OK.

Figure 20. Define the Default SIP Domain

On the right side of the Action pane, click Define Site. Enter the appropriate information, as shown in Figure 21, and then click OK.

Figure 21. Define the Site


Note that Lync Server sites have no relationship to Active Directory sites. They are completely separate and unique to Lync Server.

On the right side of the Action pane, click Define Front End Pool, and choose the radio button for the Enterprise Edition, and then click Next.

Define the pool FQDN, as shown in Figure 22. When you are done, click Next.

Figure 22. Define the Front End Pool

Define the Front End Server FQDNs and click Next.

Choose the appropriate workloads for your deployment, and then click Next. Associate the appropriate Archiving or Monitoring Servers for your pool and click Next.

Define the database and file share to be used by the pool, as shown in Figure 23. For an Enterprise deployment, SQL cannot be collocated on one of the front end servers. Also, you need to manually create the share on a server other than the front end before progressing past this step. After the share is created, Lync Server assigns the appropriate permissions. When you are ready, click Next.

Figure 23. Define SQL Instance for Front End Pool

Specify the Web Services URL for the pool and click Next.

Define an A/V Conferencing pool as shown in Figure 24.

Figure 24. Conferencing Settings

If you deploy Enterprise Voice, define a PSTN gateway if required, as shown in Figure 25. Then click Next.

Figure 25. Specify Voice Gateway

If you plan to allow external access or add any edge services, enable the Associate Edge Pool box and select an Edge Server. When complete, click Finish.

This completes the initial topology definition. However, there are additional steps to complete a fully functional topology.

Configure Simple URLs

The next step is to define easy-to-remember URLs for common Lync Server functions.

From the main Topology Builder page where your site name is highlighted, expand Simple URLs in the main pane, as shown in Figure 26, and then click Edit.

Figure 26. Expand the Simple URLs Item

Enter easy-to-remember URLs as shown in Figure 27.

Figure 27. Configured Simple URLs


The following three examples are all valid for Lync Server simple URLs:

Note that these are the only allowed syntaxes.

Port information, such as https://dialin.companyabc.com:443 is invalid. If you choose the first option, all the FQDNs need to be included as SANs on your certificates. If you choose the second or third option, note that the following virtual directory names are reserved and cannot be used as part of a simple URL:

  • ABS

  • Conf

  • LocationInformation

  • RequestHandler

  • AutoUpdate

  • cscp

  • OCSPowerShell

  • RGSClients

  • CertProv

  • GetHealth

  • ReachWeb

  • RGSConfig

  • CollabContent

  • GroupExpansion

  • RequestHandlerExt

  • WebTicket

Publish the Topology

The final step is to publish the topology to the Central Management Store. Perform the following steps to publish your topology:

In the Topology Builder Tool, in the top-level menu item in the left pane, select Lync Server, as shown in Figure 28.

Figure 28. The Top Level of Topology Builder

Click Publish Topology.

In the opening screen, click Next.

Ensure that correct Central Management Store is selected, and then click Next. This starts the publishing process and overwrites any existing topologies.

Enable the Create Other Databases box. Ensure the account used for installation has permission to perform this function. Click Next.

The Publish Topology window displays the actions being performed as shown in Figure 29. Click Finish.

Installing the Front End Role

It is important to note that if you jumped to this section before completing the previous steps, you need to go back. Preparing the server for the first Enterprise Edition server and building a valid topology in the Topology Builder tool are prerequisites to installing the Front End role. This is a different process from Office Communications Server 2007 and 2007 R2, and it involves more steps. Administrators new to Lync Server are advised to review the new features, requirements, and prequisites before beginning the installation process.

The following prerequisites are required to install the Enterprise Edition Front End role:

  • IIS with the following options:

    • Static Content

    • Default Document

    • Directory Browsing

    • HTTP Errors

    • HTTP Redirection

    • ASP.NET

    • .NET Extensibility

    • Internet Server API (ISAPI) Extensions

    • ISAPI Filters

    • HTTP Logging

    • Logging Tools

    • Request Monitor

    • Tracing

    • Basic Authentication

    • Windows Authentication

    • Request Filtering

    • Static Content Compression

    • IIS Management Console

    • IIS Management Scripts and Tools

  • Message Queueing with Directory Service Integration

After you’ve completed the steps outlined previously, the server is ready to install the Front End role. From the main Lync Server Deployment Wizard screen, click Install or Update Lync Server System from the main pane, and then click Run for Step 1: Install Local Configuration Store. Follow the steps that follow to complete the installation process:

For Step 2: Setup or Remove Lync Server Components, click Run.

As the screen that pops up, click Next.

The next screen shows the actions being performed, as shown in Figure 30. This process takes a few minutes to complete.

Figure 30. Installing the Front End Role

After the task completes, click Finish and you are brought back to the Deployment Wizard.

Review Step 3: Request, Install or Assign Certificates and click Run.

At the next screen, choose Default, as shown in Figure 31, and then click Request.

Figure 31. Request the Default Certificate

Assuming you are using an internal CA, choose Send the request immediately to an online certificate authority, and then click Next. This is the default option.

Select the appropriate CA for your environment from the drop-down list, choose a friendly name and key length, and enable the Mark the certificate’s private key as exportable box as shown in Figure 32, and then click Next.

Figure 32. Certificate Request Settings

Enter your organization name and organizational unit, and then click Next.

Select your country from the drop-down menu, and then enter your state/province and city/locality. Remember that full names must be entered, abbreviations are not considered valid for certificate requests. When complete, click Next.

The Deployment Wizard automatically adds the SANs required based on the published topology. Unless you have special requirements, select the option to Skip, and then click Next.

Review the information to ensure it is correct, and then click Next.

This screen shows the commands executed, as shown in Figure 33.

Figure 33. Certificate Request Process

Click Next.

Ensure Assign this certificate for Lync Server certificate usages is checked and click Finish.

On the first screen, click Next.

Review the certificate information and then click Next.

Figure 34 shows the actions to assign the certificate. When the actions are complete, click Finish.

Figure 34. Assigning the Certificate

After all the certificates have been assigned, a check mark by Step 3 displays, as shown in Figure 35. If there is not a check mark, check the process because you likely skipped a step.

Figure 35. Certificate Process Completed

If the file store for the pool is located on this system, you need to reboot before continuing. After the reboot, restart the Deployment Wizard by launching Setup.exe.

Click Install or Update Lync Server System, and then click Run for Step 4: Start Services.

Click Next.

Ensure all services start, as shown in Figure 36.

Figure 36. All Services Started

Click Exit to leave the Deployment Wizard.

Configure Front End

The Standard Edition front end is now installed and ready for further configuration using the Lync Server Control Panel, as shown in Figure 37. The Lync Server Control Panel is the only GUI available to Lync administrators. It is assumed that most configuration will be done via the Lync Server Management Shell.

Figure 37. Lync Server Control Panel

For Enterprise Edition deployments, you need to manually add an A record in DNS for the pool name of your front end pool. This is the FQDN that is used when you select Lync Server Control Panel from the Start menu.


Note that the client autoconfiguration requirements are still the same.

The following DNS records are required for client autoconfiguration:

  • SRV record of _sipinternaltls._tcp.<sip_Domain> for port 5061 pointing to the FQDN of your front end pool or Director

  • Host (A) record of sipinternal.<sip_Domain> pointing to the IP address assigned to your front end pool or Director

  • Host (A) record of sip.<sip_Domain> pointing to the IP address assigned to your front end pool or Director
