=====Notes=====


====0x800704DD error====

When running a scheduled task as a local administrator/user you get the following error:
<code>
The operation being requested was not performed because the user has not logged on to the network. The specified service does not exist (0x800704DD)
</code>
You can run into this if you try to run bitsadmin.exe /AddFile from a (VB)script in a scheduled task (on Windows 7).

Workaround: Create the scheduled task so that it runs under the SYSTEM account or create it as an AT job (which is basically the same as running it as a normal scheduled task under SYSTEM, but with less options).


=====Scheduled reboot======

Schedule a daily reboot of the system at 04:30:

<code>
"%SYSTEMROOT%\system32\schtasks.exe" /Create /TN "Reboot daily 0430" /TR "\"%SYSTEMROOT%\system32\shutdown.exe\" /r /t 0 /c \"Daily reboot.\"" /RU SYSTEM /SC DAILY /ST 04:30 /F
</code>


=====Scheduled start of service if not already running=====

Schedule a daily start of the Connection Broker service at 00:30 if not already running:

<code>
"%SYSTEMROOT%\system32\schtasks.exe" /Create /TN "Start Connection Broker daily 0030" /TR "\"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe\" -Command \"if (-Not (Get-Service -Name tssdis ^| Where-Object {$_.Status -eq \\\"Running\\\"})) { Start-Service -Name tssdis }\"" /RU SYSTEM /SC DAILY /ST 00:30 /F
</code>

// To end up with //
<code>\"Running\"</code>
// in the scheduled task command it needs to be defined as //
<code>\\\"Running\\\"</code>
// in the command. \\
Using ' causes the ' to be expanded to ", and , '', \', or ^' do not work to escape it.//


=====Run every minute / Custom interval=====

Set the job trigger to "Repeat taks every" and fill in the timespan yourself instead of selecting one of the predefined options.

This might nog always work, see:
