How to Set Up SSL on a Server

Under Web site identification, click Advanced.
In the Advanced Web site identification box, under Multiple identities for this Web site, verify that the Web site IP address is assigned to port 443 (the default port for secure communications), and then click OK. Optionally, to configure more SSL ports for this Web site, click Add under Multiple identities of this Web site, and then click OK.
On the Directory Security tab, under Secure communications, click Edit.
In the Secure Communications box, select the Require secure channel (SSL) check box.
