Configuring Secure Sockets Layer in IIS

The steps for configuring Secure Sockets Layer (SSL) for a site are the same in IIS 7 and IIS 6.0, and include the following:
1. Obtain a Certificate
2. Create an SSL Binding
3. Verify the SSL Binding
4. Configure SSL Settings

Obtain a Certificate
Select the server node in the tree view and double-click the Server Certificates feature in the list view:

Click Create Self-Signed Certificate… in the Actions pane.

Enter a friendly name for the new certificate and click OK.
Now you have a self-signed certificate. The certificate is marked for “Server Authentication” use; that is, it uses as a server-side certificate for HTTP SSL encryption and for authenticating the identity of the server.

Create an SSL Binding

Select a site in the tree view and click Bindings… in the Actions pane. This brings up the bindings editor that lets you create, edit, and delete bindings for your Web site.


Click Add… to add your new SSL binding to the site.

The default settings for a new binding are set to HTTP on port 80. Select https in the Type drop-down list. Select the self-signed certificate you created in the previous section from the SSL Certificate drop-down list and then click OK.

Now you have a new SSL binding on your site and all that remains is to verify that it works.

Verify the SSL Binding

In the Actions pane, under Browse Web Site, click the link associated with the binding you just created.

Internet Explorer (IE) 7 will display an error page because the self-signed certificate was issued by your computer, not by a trusted Certificate Authority (CA). IE 7 will trust the certificate if you add it to the list of Trusted Root Certification Authorities in the certificates store it on the local computer, or in Group Policy for the domain.

Configure SSL Settings

Configure SSL settings if you want your site to require SSL, or to interact in a specific way with client certificates. Click the site node in the tree view to go back to the site’s home page. Double-click the SSL Settings feature in the middle pane.

Identifying the type of installed Certificate Authority.

Click Start, click Run, type Regedit, and then press Enter

Expand HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CertSvc\

Configuration\<CA name>\CAType

Double click to CAType

CAType = 0  is installed as Enterprise Root CA
CAType = 1  is installed as Enterprise Subordinate CA
CAType = 3  is installed as Stand Alone CA
CAType = 4  is installed as Stand Alone Subordinate CA

Manually creating virtual directory for Certificate Services

When the Certificate Authority is installed before installing IIS service, the virtual directory required for accessing certificate services web page (http://<certificateserver>/certsrv) should be created manually.

To create virtual directory, open up the command prompt and run

certutil –vroot

restart IIS services and access certificate services webpage to request certificate in GUI mode.
