Notes
0x800704DD error
When running a scheduled task as a local administrator/user you get the following error:
The operation being requested was not performed because the user has not logged on to the network. The specified service does not exist (0x800704DD)
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:
"%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
Scheduled start of service if not already running
Schedule a daily start of the Connection Broker service at 00:30 if not already running:
"%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
To end up with
\"Running\"
in the scheduled task command it needs to be defined as
\\\"Running\\\"
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:
