3.2. Grant administrator access

To grant administrator permissions

  1. On the Remote Access server in the additional entry point: On the Start screen, type Computer Management, and then press ENTER.

  2. In the left pane, click Local Users and Groups.

  3. Double-click Groups, and then double-click Administrators.

  4. On the Administrators Properties dialog box, click Add, and on the Select Users, Computers, Service Accounts, or Groups dialog box, click Locations.

  5. On the Locations dialog box, in the Location tree, click the location that contains the user account of the DirectAccess administrator, and then click OK.

  6. In the Enter the object names to select, enter the user name of the DirectAccess administrator, and then click OK twice.

  7. On the Administrators Properties dialog box, click OK.

  8. Close the Computer Management window.

  9. Repeat this procedure on all Remote Access servers that will be part of the multisite deployment.

3.3. Configure IP-HTTPS for a multisite deployment

On each Remote Access server that will be added to the multisite deployment, an SSL certificate is required to verify the HTTPS connection to the IP-HTTPS web server. Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

To obtain an IP-HTTPS certificate

  1. On each Remote Access server: On the Start screen, type mmc, 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. Click File, and then click Add/Remove Snap-ins.

  3. Click Certificates, click Add, click Computer account, click Next, select Local computer, click Finish, and then click OK.

  4. In the console tree of the Certificates snap-in, open Certificates (Local Computer)\Personal\Certificates.

  5. Right-click Certificates, point to All Tasks, and then click Request New Certificate.

  6. Click Next twice.

  7. On the Request Certificates page, click the Web Server certificate template, and then click More information is required to enroll for this certificate.

    If the Web Server certificate template does not appear, ensure that the Remote Access server computer account has enroll permissions for the Web Server certificate template. For more information, see Configure Permissions on the Web Server Certificate Template.

  8. On the Subject tab of the Certificate Properties dialog box, in Subject name, for Type, select Common name.

  9. In Value, type the fully qualified domain name (FQDN) of the Internet name of the Remote Access server (for example, Europe.contoso.com), and then click Add.

  10. Click OK, click Enroll, and then click Finish.

  11. In the details pane of the Certificates snap-in, verify that a new certificate with the FQDN was enrolled with Intended Purposes of Server Authentication.

  12. Right-click the certificate, and then click Properties.

  13. In Friendly Name, type IP-HTTPS Certificate, and then click OK.

    Tip

    Steps 12 and 13 are optional, but make it easier for you to select the certificate for IP-HTTPS when configuring Remote Access.

  14. Repeat this procedure on all Remote Access servers in your deployment.

3.4. Configure the network location server for a multisite deployment

If you selected to set up the network location server website on the Remote Access server when you set up your first server, each new Remote Access server that you add needs to be configured with a Web Server certificate that has the same subject name that was selected for the network location server for the first server. Each server requires a certificate to authenticate the connection to the network location server, and client computers located in the internal network must be able to resolve the name of the website in DNS.

To install a certificate for network location

  1. On the Remote Access server: On the Start screen, type mmc, 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. Click File, and then click Add/Remove Snap-ins.

  3. Click Certificates, click Add, click Computer account, click Next, select Local computer, click Finish, and then click OK.

  4. In the console tree of the Certificates snap-in, open Certificates (Local Computer)\Personal\Certificates.

  5. Right-click Certificates, point to All Tasks, and then click Request New Certificate.

    Note

    You may also import the same certificate that was used for the network location server for the first Remote Access server.

  6. Click Next twice.

  7. On the Request Certificates page, click the Web Server certificate template, and then click More information is required to enroll for this certificate.

    If the Web Server certificate template does not appear, ensure that the Remote Access server computer account has enroll permissions for the Web Server certificate template. For more information, see Configure Permissions on the Web Server Certificate Template.

  8. On the Subject tab of the Certificate Properties dialog box, in Subject name, for Type, select Common name.

  9. In Value, type the fully qualified domain name (FQDN) that was configured for the network location server certificate of the first Remote Access server (for example, nls.corp.contoso.com), and then click Add.

  10. Click OK, click Enroll, and then click Finish.

  11. In the details pane of the Certificates snap-in, verify that a new certificate with the FQDN was enrolled with Intended Purposes of Server Authentication.

  12. Right-click the certificate, and then click Properties.

  13. In Friendly Name, type Network Location Certificate, and then click OK.

    Tip

    Steps 12 and 13 are optional, but make it easier for you to select the certificate for network location when configuring Remote Access.

  14. Repeat this procedure on all Remote Access servers in your deployment.

To create the network location server DNS records

  1. On the DNS server: On the Start screen, type dnsmgmt.msc, and then press ENTER.

  2. In the left pane of the DNS Manager console, open the forward lookup zone for the internal network. Right click the relevant zone and click New Host (A or AAAA).

  3. On the New Host dialog box, in the Name (uses parent domain name if blank) box, enter the name that was used for the network location server for the first Remote Access server. In the IP address box, enter the intranet-facing IPv4 address of the Remote Access server, and then click Add Host. On the DNS dialog box, click OK.

  4. On the New Host dialog box, in the Name (uses parent domain name if blank) box, enter the name that was used for the network location server for the first Remote Access server. In the IP address box, enter the intranet-facing IPv6 address of the Remote Access server, and then click Add Host. On the DNS dialog box, click OK.

  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.

3.5. Configure DirectAccess clients for a multisite 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.

Remove Windows 7 clients 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.

Important

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.

3.6. Enable the multisite deployment

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.

To enable a multisite configuration

  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.
