SophosUpdateMgr - Pre-authentication failed messages in event log

Hi All

Event logs on my Servers are filling up with this error (for a whole range of different addresses) but I can't determine why. Our workstations seem to be updating OK from the Enterprise Console.

Pre-authentication failed:
    User Name:   SophosUpdateMgr
    User ID:        MyDomain\SophosUpdateMgr
    Service Name:   krbtgt/MyDomain
    Pre-Authentication Type:   0x0
    Failure Code:   0x19
    Client Address:    x.x.x.x

Any clues?

Thanks

Hello Autotype,
that's expected behaviour :smileywink: - please see EventID 675 Failure Code 0x19 on Microsoft's Technet.
The ratio should be no surprise though as this account is used by all your clients at regular intervals.
