Security Event 534 Login Type 4

[Richard Schaefer]

I have a scheduled task that uses a standard domain/userid
to execute. The task runs fine when I run it via Start-

Control Panel->Scheduled Tasks, select the task and

select Run. When the task tries to run at it's scheduled
time I get an error in the Event Log: Security Event 534,
Login Type 4. This userid is listed in the Server's
Administrator Local Group.

Can anyone tell me what a "Type 4" is? I can't find any
doc that breaks the event log entries down to that level.
What do I need to do to get these tasks running again? Do
I need to set some security policy setting to allow this
userid to run as a scheduled task?

The problem was caused by a wiseacre sysadmin who decided
to add a popup message to the standard login script. The
userid that runs the automated tasks uses this script
running disconnected so the popup caused a login failure.
I had him take the popup out and it fixed the problem.
