Challenge

Veeam ONE raises the following event-based alarm: Bad Hyper-V username logon attempt.

Cause

The Bad Host Username alert suggests that someone is attempting to access the host with an invalid username or password.

Solution

Veeam ONE raises the Bad Hyper-V username logon attempt alarm based on the Hyper-V event that is received from the MS Hyper-V host:

The further issue troubleshooting should be performed on the MS Hyper-V server side.
