Yes , that's what i thought . But I take Full backups every 3 days and diffs everyday. And the LS is out of sync for like a week now. It may be easier for me to reconfigure the whole log-shipping setup. Doesn't take much time though.

Is there anyway i can restore the last full backup + last diff backup + all the trans log backups to the Secondary log shipped database and put it back to sync.

Right now the database is in Standby/Read only mode.

Appreciate the help...
