In a Windows 2008 server, when you confirm the creation of a new task, you may obtain the following error:
An error has occurred for task <TaskName>. Error message: The following error was reported: 2147943712.
This error message occurs when Windows was unable to store credentials (expecially the password) of the user who run the task; normally a security policy doesn’t allow this.
Open Local Security Policy (in Administrative Tools from the Start menu or from Control Panel) and set Disabled the following element:
Network Access: Do not allow storage of passwords and credentials for network authentication
Network access: Do not allow storage of credentials or .NET Passports for network authentication
https://technet.microsoft.com/en-us/library/cc779377(WS.10).aspx
This security setting determines whether Stored User Names and Passwords saves passwords, credentials, or .NET Passports for later use when it gains domain authentication.
If it is enabled, this setting prevents the Stored User Names and Passwords from storing passwords and credentials.
Note
When configuring this security setting, changes will not take effect until you restart Windows.
For more information about Stored User Names and Passwords, see Stored User Names and Passwords.
Default: Disabled.
Configuring this security setting
You can configure this security setting by opening the appropriate policy and expanding the console tree as such: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\
For specific instructions about how to configure security policy settings, see Edit security settings on a Group Policy object.
