|This topic describes deployment of DirectAccess in Windows Server 2008 R2. For deployment of DirectAccess in Microsoft Forefront Unified Access Gateway (UAG), see the Forefront UAG DirectAccess Deployment Guide (http://go.microsoft.com/fwlink/?LinkId=179989).|
The DirectAccess server needs a customized Secure Sockets Layer (SSL) certificate to authenticate Internet Protocol over Secure Hypertext Transfer Protocol (IP-HTTPS)-based DirectAccess connections.
To complete these procedures, you must be a member of the local Administrators group, or otherwise be delegated permissions to request and customize an SSL certificate. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).
On the DirectAccess server, click Start, type mmc, and then press ENTER. Click Yes at the User Account Control prompt.
Click File, and then click Add/Remove Snap-ins.
Click Certificates, click Add, click Computer account, click Next, select Local computer, click Finish, and then click OK.
In the console tree of the Certificates snap-in, open Certificates (Local Computer)\Personal\Certificates.
Right-click Certificates, point to All Tasks, and then click Request New Certificate.
Click Next twice.
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 DirectAccess server computer account has enroll permissions for the Web Server certificate template. For more information, see Configure Permissions on the Web Server Certificate Template.
On the Subject tab of the Certificate Properties dialog box, in Subject name, for Type, select Common name.
In Value, type the fully qualified domain name (FQDN) of the Internet name of the DirectAccess server (for example, da1.contoso.com), and then click Add.
Click OK, click Enroll, and then click Finish.
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.
Right-click the certificate, and then click Properties.
In Friendly Name, type IP-HTTPS Certificate, and then click OK.
|Steps 12 and 13 are optional, but make it easier for you to select the certificate for Secure Hypertext Transfer Protocol (HTTPS) connections in Step 2 of the DirectAccess Setup Wizard.|
|The DirectAccess Setup Wizard by default configures the URL of the IP-HTTPS server in the DirectAccess client and server GPOs based on the following format: https://SubjectFieldIP-HTTPSCertificate:443://IPHTTPS. This URL must not be more than 256 characters long. Otherwise, the IP-HTTPS component on the DirectAccess client and server will not operate correctly. Therefore, the FQDN in Step 9 of this procedure must not be more than 234 characters.|
