GlobalTrust send more than one certificate. In addition to the certificate for your server GlobalTrust send an Intermediate CA Certificate (the Comodo certificate) and a Root CA Certificate (GTE CyberTrust). Before installing the server certificate, install both of these certificates. Follow the instructions in 'Storing a CA certificate'.

Note: If the authority who issues the certificate is not a trusted CA in the key database, you must first store the CA certificate and designate the CA as a trusted CA. Then you can receive your CA-signed certificate into the database. You cannot receive a CA-signed certificate from a CA who is not a trusted CA. For instructions see 'Storing a CA certificate'.
