Last week I attempted to add a scheduled task to my Windows 2008 server using schtasks.exe. The syntax I used was:

schtasks /create /S server /U DOMAIN\ACCOUNT /P password /SC daily /ST 15:00 /TN BkupIIS /TR c:\scripts\bkupiis.cmd

I received the following message from schtasks.exe:

Table of Contents
    User credentials are not allowed on the local machine

    The task scheduler log file shows the following error:

    Task Scheduler failed to start "\BkupIIS" task for user "DOMAIN\ACCOUNT". Additional Data: Error Value: 2147750687.

    The secret to successfully scheduling the task is to use /RU and /RP instead of /U and /P.

    The syntax that should be used to create the scheduled task is:

    schtasks /create /S server /RU DOMAIN\ACCOUNT /RP password /SC daily /ST 15:00 /TN BkupIIS /TR c:\scripts\bkupiis.cmd
