To import a CA certificate from Microsoft certificate services
On the sender computer requiring a CA certificate, open your browser.
In your browser, connect to http://<servername>/certsrv, where <servername> is the name of the server where the certification authority (CA) you want to access is located.
Click Download a CA certificate, certificate chain, or CRL.
Select the encoding method you want: DER or Base 64.
Do one of the following:
If you want to trust only the certificates issued by this certification authority, and not any subordinate certification authorities, click Download CA certificate.
If you want to trust all the certificates issued by this certification authority (CA), click Install this CA certificate chain.
In File Download, click Open.
When the Certificate dialog box appears, click Install this certificate.
In the Certificate Import wizard, click Automatically select the certificate store based on the type of certificate. This places the CA certificate in the Trusted Root store.
If you are finished using the Certificate Services Web pages, close your browser.
