SophosSAU

Hi everyone,

We have SEC 4.5 installed on Windows Server 2008 x64.

The issue we have is that our audit software detects unsuccessful logins from few PC's in the network from the Local User SophosSAU*COMPUTERNAME*0 .

Can somebody explain why is this happening, why we do not get successful logins logs, what is the difference between SophosSAU*COMPUTERNAME*0 and SophosUpdateManager user.

Here is the log...

DOMAINNAME Network x.x.1.66 COMPUTERNAME 4625 failure
