I have the maintenance plan for the daily full backup and log backup . It has failed for last two days. the error in the logs shows the following message
BackupDiskFile::CreateMedia: Backup device '\\mnsql01\sqlbackups\mnncdbprod01\full\rgsdyn_backup_2012_03_29_201531_3880704.bak' failed to create. Operating system error 86(The specified network password is not correct.).
I don;t know anything has changed (at least one body informed me). Can you suggest what should i do . How to fix the issue so that it won;t fail today?
