Re: Windows Task Scheduler looses account credentials data

Hi,

Here are some suggestions:

Go to Start/Run/Msconfig. Click Selective Startup and uncheck Load System Services, click ok. Reboot.

Upon reboot, click OK to the first Window that indicates that you have selected "Selective Startup". When the System Configuration Utility reappears, Check the Normal
Startup Box.

Then go to Start/Search and type in: schedlgu.txt. When it appears, right click on the file and delete it. Reboot.

You will now have a new Task Scheduler Log File. It can be checked by going to Start/Search and typing in: schedlgu.txt. Appearing will be your new Task Scheduler Log.

Running Scheduled Tasks without a password:

For Pro: Start/Control Panel/Administrative Tools/Local Security Policy/Local Policies/Security options. In the right hand pane (third down).

Accounts: Limit local account use of blank passwords to console logon only. This is enabled by default, disable it.

For Home: Run Scheduled Task without a Password (Line 68)

Hello,

I have spent many hours trying to find the solution for this problem. I have found several discussions on IT forums with very similar or exact same problem. For instance:

http://www.realgeek.com/forums/task-scheduler-unreliable-nt-2000-xp-420027.html

Here is my problem described by someone else:

I have encountered a problem with Windows Task Scheduler at many
client sites over the years, where tasks may run flawlessly for days
or weeks, then magically - they stop running (listing "Could Not
Start" for the task's status). To correct the problem, I simply have
to re-enter the task's password - the SAME password that has always
been there. The task will then run for several more days/weeks! This
has been a problem in Windows NT 4.0(sp6a) SERVERs AND XP Prof
workstations. And no surprise, since XP probably uses some of the
same underlying code as NT! I have talked with other consultants -
and we've all concluded that Microsoft's task scheduler is "unreliable
at best". I would love to find out the real cause of the problem and
solve this once and for all... More info: generally a single domain
exists, YES user account associated with task ALWAYS has/had a
password...

SchedLog.txt reports: The attempt to retrieve account information for
the specified task failed; therefore, the task did not run. Either an
error occurred, or no account information existed for the task. The
specific error is: 0x8004130f: No account information could be found
in the Task Scheduler security database for the task indicated.

How does Windows lose the "account information"? I can log in as the
same user assigned to the task - without a problem!

In my own case the Task Manager log says:

12/2/2008 1:25:17 PM ** ERROR **

The attempt to log on to the account associated with the task failed, therefore, the task did not run. The specific error is:

0x80070569: Logon failure: the user has not been granted the requested logon type at this computer. Verify that the task's Run-as name and password are valid and try again.



There are several "solutions" on the forums like verifying group policy, disabling 3rd party services, day light saving time changing effect and some others. Neither works for my situation.

As I understand the problem has existed for years and generations of Windows. I am curious if MS ever provided real solution for this. Once more: the scheduled task on XP runs for weeks\months normally under the domain admin account. The password is never changed on this account. Suddenly the task stops running with description from above. I reapply the password and it works again.

Thank you

Eugene
