Consistent Schannel Errors on Windows Logs


Event ID 36882: The Certificate Received From the Remote Server Was Issued By an Untrusted Certificate Authority.

Because authentication relies on digital certificates, certification authorities (CAs) such as Verisign or Active Directory Certificate Services are an important part of TLS/SSL. A CA is a mutually-trusted third party that confirms the identity of a certificate requestor (usually a user or computer), and then issues the requestor a certificate. The certificate binds the requestor’s identity to a public key. CAs also renew and revoke certificates as necessary. For example, if a client is presented with a server’s certificate, the client computer might try to match the server’s CA against the client’s list of trusted CAs. If the issuing CA is trusted, the client will verify that the certificate is authentic and has not been tampered with.

The Schannel provider creates the list of trusted certification authorities by searching the Trusted Root Certification Authorities store on the local computer. When Schannel detects a certificate that was issued by an untrusted certification authority, this error is logged.

The issue could be due to improper import of SSL CA.

Resolution : Re-import the certificate and monitor further.

Tail Log Backups

Tail log backups capture the tail of the log even if the database is offline, damaged, or missing data files. This might cause incomplete metadata from the restore information commands and msdb. However, only the metadata is incomplete; the captured log is complete and usable. If a tail-log backup has incomplete metadata, in the backupset table, has_incomplete_metadata is set to 1. Also, in the output of RESTORE HEADERONLY, HasIncompleteMetadata is set to 1. To create a tail log backup, use below script BACKUP LOG [DB Name]    TO [TLog_Device_Location]      WITH NO_TRUNCATE;   GO Scenarios That Require a Tail-Log Backup If the database is online and you plan to perform a restore operation on the database, begin by backing up the tail of the log.
