You can use this procedure to configure Group Policy to automatically enroll client computer certificates and deploy them to the workstations on your network. Follow this procedure for each GPO that contains IPsec connection security rules that require this certificate.
To complete these procedures, you must be a member of both the Domain Admins group in the root domain of your forest and a member of the Enterprise Admins group.
To configure Group Policy to autoenroll certificates
On a computer that has the Group Policy Management feature installed, click Start, click Administrative Tools, and then click Group Policy Management.
If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
In the navigation pane, expand Forest: YourForestName, expand Domains, expand YourDomainName, expand Group Policy Objects, right-click the GPO you want to modify, and then click Edit.
In the navigation pane, expand the following path: Computer Configuration, Policies, Windows Settings, Security Settings, Public Key Policies.
Double-click Certificate Services Client - Auto-Enrollment.
In the Properties dialog box, change Configuration Model to Enabled.
Select both Renew expired certificates, update pending certificates, and remove revoked certificates and Update certificates that use certificate templates.
Click OK to save your changes. Computers apply the GPO and download the certificate the next time Group Policy is refreshed.
