Installing Server Certificates (IIS 6.0)
After you have obtained a server certificate, you can install it. When you use the Server Certificate Wizard to install a server certificate, the process is referred to as assigning a server certificate.
You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /user:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
To install a server certificate using the Web Server Certificate Wizard
When you use the Web Server Certificate Wizard to assign a certificate, you must specify a password before the certificate can be assigned to your Web server.
