When I try to schedule a task, I get the following error: error 0x8007007a the data area pased to a system call is too small. I followed the steps in Q264522, but still get same error. Is there a fix or workaround?Thanks...Joe1 person needs an answerI do too

Hi,1. What kind of task are you trying to schedule?2. By any chance is your computer on a domain?There is a possibility that another application might be causing a conflict. You are required to perform a clean boot to find the program that is causing this and then disable or remove it.How to configure Windows XP to start in a "clean boot" statehttp://support.microsoft.com/kb/310353/en-usNote: After you have finished troubleshooting, follow the steps as explained in the article to reset the computer to start as usual.

Thank you Shekhar. I will try this and see if it helps. I was trying to schedule a disk defrag when getting this error and also noticed that Ad-Aware auto updates and auto scan had not been running. I will let you know and thanks again...Joe

Hi Shekhar, I completed steps 1-3 of configuring to clean boot state, and still got the error when trying to schedule disk defrag. I then completed step 4 and at least got a different error, telling me task is scheduled but can't complete because task scheduler isnt running. I'm hopeful now that it will work, I will know Wedneday at 3pm when I scheduled it to run. Thanks for your help and I'll let you know if it works or not...Joe

Why don't you just create one simple task to run something easy like the command prompt, get that working and then you will know that you Scheduled Task mechanism and functions are working completely through from end to end.If the simple Scheduled Task does not work, figure out why and fix it.When you are sure that your simple task works, then take the knowledge and troubleshooting skills you learned and apply them to your defrag task.You do not have to wait until Wednesday, and I can tell you that if you are scheduling a defrag, that sometimes needs some fine tuning (especially if you are using the built in Windows defragmenter). Did you read this MS article yet? The article it not entirely accurate in my opinion, but it will help you get started, then you can fix it to work they way you want.http://support.microsoft.com/kb/555098 One day, I made some copy/paste notes to help someone that could not get a Scheduled Task to work (of course they did get it working):It is strongly suggested (but not required) that the task be assigned to a user that has a password (using the Administrator account is not recommended), so create a new user with a password just for tasks or add a password to your account if needed.You can temporarily assign yourself a password to test and worry about this later. Right now you just need to see if your ST mechanism is working properly, so go ahead and create yourself a login password - at least temporarily and you can fix it later.If you set up the task to use the same account you log in with, you will usually be able to see the task launch and start running while you are using the computer. This is helpful but it can be annoying if the task starts when you are in the middle of doing something else.If you set up the task to use a different account than the one you log in with the task should still run (and you will not "see" it interrupt you), but for testing, use your own login account and then change the account the task uses later when you are sure it all works.If you try to create a new task using an account that does not have a password you will get this error trying to create the task:The new task has been created, but may not run because the account information could not be set. The specific error is 0x80070005: Access is denied.The task will still be created, but will not run properly. There is a way around this, but get this working first to be sure your Scheduled Task mechanism is not afflicted.Stop the Task Scheduler service. Click Start, Settings, Control Panel, Administrative Tools, Service and locate the Task Scheduler Service andstop it.Delete or rename the probably cluttered Scheduled Task log file which is usually found here: c:\windows\schedlgu.txt Restart the Task Scheduler service to create a new log (it is just a text file) and verify that a new log file has been created and looks something like this:"Task Scheduler Service" Started at 1/1/2010 6:26:43 AM[ ***** Most recent entry is above this line ***** ]Navigate to the c:\windows\tasks folder to see all your tasks. Expand the explorer window so you can see all the columns of interest dragging thecolumn headings to see each column.The Next Run Time, Last Run Time, Status and Last Results columns are of interest. You can also click Advanced and view the ST log file from here.Choose to Add Scheduled Task. Create a new task to run Command Prompt once, right now. If you don't have a password on your account, you will getan error trying to create it (more on that later). The new task will still be created, but it will never run. Assign a password to your account at least temporarily to test your Scheduled Task mechanism.Having temporarily assigned your login account a password, adjust the new Scheduled Task you created to run the Command Prompt so it uses the same account and password you used to login to Windows and the task should configure and save with no errors.Right click the new Command Prompt task and choose Run and a command window should open immediately. If not, something is wrong. If yes, your mechanism is sound. Look in the log file to see your results.Since the Command Prompt task is set up to run under your account, this is why you will see the Command Prompt window open right away. If youconfigured the task to use some other account (with a password of course), the Command Prompt task would run under that users name (not yours) and youwould not see the Command Prompt window open, but the task would be running and you can see it in Task Manager. This way you know your ST mechanism is working.Now that you know how to run tasks manually, know how to observe the information columns, know how to remove the log file, you can apply this knowledge to your new task. Be sure the Task Scheduler service is running again if you stop it to remove the log file while testing.Assign Properties to your new or troublesome task that match your login (at least for testing), observe the columns, and the log. If your task fails to run manually, the errors in the log file are the clues to what to do next.Always try to go back to your simple Command Prompt task that you created before to make sure the ST mechanism works properly - you know for sure that one works. Then apply your knowledge to get your new task working.You can change the task Properties to use your login account and password since you know it works properly on the Command Prompt task. If you change your new task and choose to run it and are logged in with the same account, you should see your task run. When you are satisfied it is working properly, you probably don't want to have it interrupt you while you are logged in, so change the Properties back to use some other user account login that has a password that you created just to run your scheduled tasks.Some tasks that are created by other applications will use the special account NT AUTHORITY\SYSTEM. This account has no password and is usually used for system oriented tasks but you will only be able to see it running when using Task Manager. If you try to manually run a ST like this, you will not see it open any window to run but you will see it running in Task Manager and in the log file. If you think you want to see it actually run, change the Properties to use your account and password, troubleshoot the task, then change the Properties back and test it again.These kinds of tasks may run just fine, but you will only be able to tell by the log file, looking in Task Manager or the status columns in the tasks folder. If you temporarily change the task to use the same account and password you use to login, you will be able to watch it run.Once you understand how to get a simple task like Command Prompt working and you know where the log file is and how to change the task Proprieties, you can work on your new or afflicted task and get it working.There are ways to work around some of the restrictions and requirements, but it is best to just use what you have and use it properly.Do, or do not. There is no try.I decided to save up points for a new puppy instead of a pony!

Thanks Jose, good troubleshooting suggestion. I'll read back through your suggestion and try to get a simple task working. The error you mentioned is what i get when I use my account which is an administrator account. I'll read the article and follow your suggestion and see what happens. thanks again, Joe

Istill get the same error after performing all of the steps and clean boot. I appreciate the suggestion and I did get something else to try from another member. Thanks again...Joe

I tried your suggestion same trouble. I can't run command prompt by clicking from scheduled tasks. Must be a problem with my old load of XP Home. I need to upgrade anyway. Thanks...Joe

It doesn't matter if it is an Administrator account. What matters is to use an account that has a password. If you use an Administrator account with no password, you will have difficulty.You can fix the task later to not use a password, but all you want to do it get it working first.If you create the task to run with your login account, and your login account does not have a password, apply a password to your login account just to get the simple task working... or create a new Administrator account and put a password on it and use that to create your Command Prompt scheduled task.If it doesn't work, you can post up the contents of the Scheduled Task log file where you try to run the task manually and we can have a look and see what is going on and fix it.Do, or do not. There is no try.I decided to save up points for a new puppy instead of a pony!
