I get this failure audit in my log every time I log in to my W2K SP4
domain from my XP SP1 workstation.

Event Type: Failure Audit
Event Source: Security
Event Category: Privilege Use
Event ID: 577

Any ideas on tracking this down would be most appreciated.

Note that the failure audit means that you don't have that privilege, which
is, in and of itself, normal.

Are you running any programs that might try to perform system logons, or
create new process tokens?
The TCB privilege used to be required to call the LogonUser API, but with XP
this is no longer the case.

Dave, thanks for the response.

I am not aware of any software on my box that would require system
logons. My software is pretty well mainstream. Is there any way to
identify the program?

What types of programs require new process tokens?

If you mean virus scanners, I suppose anything's possible, but it seems very
unlikely.
If you mean a hacker, it seems more likely, though still not very. Does
this information look legitimate?

....is PETER1 your XP machine? Do you have anything interesting in your
Startup folder or in the registry under HKLM\Software\Microsoft\Windows\Run?

If all else fails, you can configure an audit policy on PETER1 to enable
process tracking, logoff and log back on. This should give you a rough
indication of what process (if any) is causing this. From there you can try
to find out what that process is doing.

System processes and services generally-- it probably won't be a service,
though, because most older services install as LocalSystem, which is granted
the TCB privilege already.
