GetActiveObject called from a protected mode process fails with Operation unavailabe (0x800401E3) RRS feed

  • Question

  • I have a singleton regsitered in the ROT create in process A. I have put process A in the \Low Rights\ElevationPolicy key. But when I try to access the object using GetActiveObject from a protected mode process, the call fails with Operation unavailabe (0x800401E3).

    It works fine from a medium intergrity process. Note process A is a medium integrity process.

    Any help would be appreciated?

    Thanks,

  • Hello cgsolution,

    What build are you running this on? Can you send me some sample code that will reproduce this? What do you mean by a protected mode process. Process Isolation in Vista will not allow a lower IL process to communicate with a higher IL process. What happens if you try this on equal IL processes?

     

    Thanks!
