Periodically following error is logged in Windows Server 2008 Administrative events: The certificate received from the remote server was issued by an untrusted certificate authority. Because of this, none of the data contained in the certificate can be validated. The SSL connection request has failed. The attached data contains the server certificate. Log Name: System Source: Schannel Followed by: The following fatal alert was generated: 48. schannel fatal alert The internal error state is 552. Log Name: System Source: Schannel If i change the Force Encryption property in SQL-Server Configuration from "No" to "Yes"(see image below) the error would not be logged anymore. But i don't really need SSL-Encryption since all connections are trusted(from intranet) and ports 1333 and 1334 are firewalled from internet. Would it be a performance impact if i would force encryption and generate a server certificate, is it recommended at all in my situation? I don't want to enforce encryption only to prevent from some event logs if it not even causes serious connection problems(where can i see which connection has caused it?).

To find which remote resource your server is trying to access, in Event Viewer, open the Details tab of the event (use the Friendly View). Here the EventData contains the SSL certificate received. To understand the EventData, scroll down until you see the section In Bytes. Here
