How to Configure Certificates for Party Resolution
When you use BizTalk Explorer to configure a party, you can configure the party so that the party is resolved by using its digital signature. If you configure the party this way, when BizTalk Server receives a message, it will use the public key certificate to determine who sent the message, and to resolve the sender to a known party in the BizTalk Server environment.
To perform the procedure in this topic, you must be logged on as a member of the BizTalk Server Administrators group.
