Login failed for user ethosys

[3rdJoey]

I am getting this event on our sql server

Category 4 event id 18456


Login failed for user 'ETHOSYS'. [CLIENT: 192.168.x.xxx]

Environment

sql enterprise 2005
Microsoft clustering

It appears often and it has different ip addresses associated with it. Not any one particular ip address but they are all local to our domain. It appears on the logs of both nodes in the cluster.

Thanks,
