SophosUpdateMgr - Pre-authentication failed messages in event log

Autotype

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

    Hi Cristian

    There are hundreds of these events and still occuring.  Yes I can see this message generated from other accounts but the ratio is hugely in favour of SophosUpdateMgr.

    Desktops generating logs events all appear to be Win7.  AD Server is 2003.

    Thanks
