  5. Repeat steps 3 and 4 for every Remote Access server in your deployment.

  6. Click Done.

  7. Repeat this procedure before adding servers as additional entry points in the deployment.

DirectAccess Windows client computers must be members of security group(s) which define their DirectAccess association. Before multisite is enabled, these security group(s) can contain both Windows 8 clients and Windows 7 clients (if the appropriate “downlevel” mode was selected). Once multisite is enabled, existing client security group(s), in single server mode, are converted to security group(s) for Windows 8 only. After multisite is enabled, DirectAccess Windows 7 client computers must be moved to corresponding dedicated Windows 7 client security groups (which are associated with specific entry-points), or they will not be able to connect over DirectAccess. The Windows 7 clients must first be removed from the existing security groups which are now Windows 8 security groups. Caution: Windows 7 client computers that are members of both Windows 7 and Windows 8 client security groups will lose remote connectivity, and Windows 7 clients without SP1 installed will lose corporate connectivity as well. Therefore, all Windows 7 client computers must be removed from Windows 8 security groups.

  1. On the primary domain controller, click Start, and then click Active Directory Users and Computers.

  2. To remove computers from the security group, double-click the security group, and on the <Group_Name> Properties dialog box, click the Members tab.

  3. Select the Windows 7 client computer, and click Remove.

  4. Repeat this procedure to remove the Windows 7 client computers from the Windows 8 security groups.

ImportantImportant
When enabling a Remote Access multisite configuration all client computers (Windows 7 and Windows 8) will lose remote connectivity until they are able to connect to the corporate network directly or by VPN to update their group policies. This is true when enabling multisite functionality for the first time, and also when disabling multisite.

To configure a multisite deployment, enable the multisite feature on your existing Remote Access server. Before enabling multisite in your deployment, make sure you have the following information:

  1. Global load balancer settings and IP addresses if you want to load balance DirectAccess client connections across all entry-points in your deployment.

  2. The security group(s) containing Windows® 7 client computers for the first entry point in your deployment, if you want to enable Remote Access for Windows 7 client computers.

  3. Group Policy Object names, if you are required to use non-default Group Policy Objects, which are applied on Windows 7 client computers for the first entry point in your deployment, if you require support for Windows 7 client computers.

Do this step using Windows PowerShell

  1. On your existing Remote Access server: On the Start screen, type RAMgmtUI.exe, and then press ENTER. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.

  2. In the Remote Access Management Console, click Configuration, and then in the Tasks pane, click Enable Multisite.

  3. In the Enable Multisite Deployment wizard, on the Before You Begin page, click Next.

  4. On the Deployment Name page, in Multisite deployment name, enter a name for your deployment. In First entry point name, enter a name to identify the first entry point which is the current Remote Access server, and then click Next.

  5. On the Entry Point Selection page, do one of the following:

    • Click Assign entry points automatically, and allow clients to select manually to automatically route client computers to the most suitable entry point, while also allowing client computers to select an entry point manually. Manual entry point selection is available only for Windows® 8 computers. Click Next.

    • Click Assign entry points automatically to automatically route client computers to the most suitable entry point, and then click Next.

  6. On the Global Load Balancing page, do one of the following:

    • Click No, do not use global load balancing if you do not want to use a global load balancing, and then click Next.

      noteNote
      When selecting this option client computers connect to their closest entry point automatically.

    • Click Yes, use global load balancing if you want to load balance the traffic globally between all entry points. In Type the global load balancing FQDN to be used by all entry points, enter the global load balancing FQDN, and in Type the global load balancing IP address for this entry point that contains the first Remote Access server, enter the global load balancing IP address for this entry point, and then click Next.



  7. On the Client Support page, do one of the following:

    • To limit access to client computers running Windows 8 or later operating systems, click Limit access to client computers running Windows 8 or a later operating system, and then click Next.

    • To allow client computers running Windows 7 to access this entry point, click Allow client computers running Windows 7 to access this entry point, and click Add. On the Select Groups dialog box, select the security group(s) that contains the Windows 7 client computers, click OK, and then click Next.

  8. On the Client GPO Settings page, accept the default GPO for Windows 7 client computers for this entry point, type the name of the GPO that want Remote Access to create automatically, or click Browse to locate the GPO for Windows 7 client computers, and then click Next.

    noteNote
    • The Client GPO Settings page appears only when you configure the entry point to allow Windows 7 client computers to access the entry point.

    • You can optionally click Validate GPOs to ensure that you have the proper permissions for the selected GPO or GPOs for this entry point. If the GPO does not exist and will be automatically created, then create and link permissions are required. In the case where the GPOs were created manually, then edit, modify security, and delete permissions are required.

  9. On the Summary page, click Commit.

  10. On the Enabling Multisite Deployment dialog box, click Close and then on the Enable Multisite Deployment wizard, click Close.
