From: Shri.DBA on

I have job to take transaction log backup. The job failed with the below
error message "
Msg 49999, Sev 19: Failed to login to SQL Server [SQLSTATE HY000]
Msg 0, Sev 19: 2006-10-06 05:04:01 Log backup of 'Products' to
f:\mssql$viper\backup\Products\SQLTST22_PRODUCTS.PRODUCTS.Log.SLP.20061006050401.BAK. [SQLSTATE 01000]"

The job ran successfully from the next run.

I am not able to find out the exact cause of the failure. Can some help me
identifying what should be exact reason for the failure.
