Task Scheduler Service broken in Windows XP Professional SP2

[vincepoy]

Greetings everyone:

My Task Scheduler Service under Windows XP Professional SP2 for the
last few years and then all of a sudden, it just fails to work
correctly. I have deleted all taks to make sure it isn't corrupted
tasks that is causing it.

The registry keys appears to be correct as well when I compared them:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Schedule]
"Description"="Enables a user to configure and schedule automated
tasks on this computer. If this service is stopped, these tasks will
not be run at their scheduled times. If this service is disabled, any
services that explicitly depend on it will fail to start."

In the Event Viewer -> System, it shows as the only error:

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7023
Date: 9/24/2007
Time: 4:40:44 PM
User: N/A
Computer: LUNAR
Description:
The Task Scheduler service terminated with the following error:
Unspecified error

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.

When I tried to launch the service from the command prompt, I get:

C:\Documents and Settings\vince>net start schedule
The Task Scheduler service is starting.
The Task Scheduler service could not be started.

A system error has occurred.

System error 16389 has occurred.

The system cannot find message text for message number 0x4005 in the
message fil
e for BASE.

the following services are running:

Event Log
Protected Storage
Remote Procedure Call (RPC)
Remote Procedure Call (RPC) Locator

When I used Symantec's Process Viewer to look at the svchost.exe
process that executes as:
C:\WINDOWS\System32\svchost.exe -k netsvcs
It shows that C:\Windows\System32\schedsvc.dll is running in memory as
a module.

So I don't know how to I go about troubleshooting this and fixing it
as I am not sure what is causing the error. I did not install or
remove anything since it was working.

Thanks for any assistance in advance!

Cheers,
Vince

Go here and scroll down to the Task Scheduler section for many helpful
hints. (About 1/5 of the way down the page.)

Hi Vince,

I can't give you a fix, but perhaps another reasons for the cause. I just
had the same problem with task scheduler trying to schedule a future back up.
I posted the nature of the problem today under the Windows XP Security and
Administration category. One cause might be a Windows security update. The
recommended hotfix did not work. See MS Knowledge Base Artice 904423.
Good Luck
