Can't restart mirroring. Error 1416 and 1443.

After stop mirroring, can't restart mirroring. Tried following two things, still can't restart mirroring.

1. Made a full DB backup and a log backup on principle, copied backup files to mirror and restored DB and log with NORECOVERY. Mirror DB is in "Restoring" status.

2. Delete DB on both principle and mirror, recreate DB on the principle, restore DB and log on the mirror with NORECOVERY. Mirror DB is in "Restoring" status.

In both cases, after clicked "Start Mirroring", got error 1416. In sql server log file, got error 1443 ("Database mirroring has been terminated..."). Please help.Never mind. Problem solved.|||How did you solve this - I get the same problem (using certificates for authorization of logins - Domain server not vaible in my situation)

Thanks
