Logon Password — /P password

If this parameter is specified, Content Manager OnDemand uses the value as the password for the initial user logon.

This parameter can be used in combination with the Logon Server Name and Logon User ID parameters to logon the user during initialization. If all three parameters are specified and are valid, the initial Logon dialog box is not displayed.

C:\<install dir>\arsgui.exe /S pikes  /U user1

where <install dir> is your OnDemand Client installation directory path.
