Ability to run scripts from the SCCM server, like a built in Web Service
Adding the ability to run powershell scripts on a SCCM site server when called from a Task Sequence or Compliance item.
Some scripts need special rights or modules that are not available to Users or client devices. (ActiveDirectory, ConfigManager actions)
Being able to add these scripts in the SCCM console and have them ran from a call back from the client or Task Sequence would save running multiple Web Services on the server.
