Microsoft Windows host process (Rundll32)

    Microsoft Windows host process (Rundll32)

    OS: Windows VISTA Business - 32 bit

    RAM: 6GB RAM (only 3 able to be fully utilized because of OS limitations) -

    Processor: Dual Core, Workstation class machine, experience index 5.0,
    Intel® Xeon® CPU 5130 @ 2.00 GHZ 1.99 GHz. 3 months old.



    Problem (or perceived problem): The following Microsoft Windows service
    appears (i.e. inside Windows Defender) to be running 3 times. All three
    instances show the exact same file name and version - Microsoft Windows host
    process (Rundll32), File Version: 6.0.6000.16386 (vista_rtm.061101-2205).



    Is this reasonable or should I try to find and disable the starting of the
    last two instances of this?



    The machine has been sluggish (considering the hardware) and I am trying to
    clean it up by removing unnecessary services and applications and related
    DLLs. This service appears to be running 3 times and I am not sure whether
    this is correct or the remnant of something I have removed.



    Thanks, Will

    If Rundll32 is running out of the System32 directory then it's legit, and if
    it's not running out of the System32 directory, then it's a Trojan.

    run32dll.exe will be call upon it to host dll(s) for the application. It's
    being used all over the place in running applications to host Dll(s) the
    applications needs.

    You want to see what is happening, then run Process Explorer to see what a
    process is hosting. View menu Show lower pane and Lower pane view/dll will
    show everything that being hosted for a process in the upper pane when you
    click on it. You can right-click and go to Properties for more info, and you
    can do the same thing in the lower pane.

    Hi, Will,

    Rundll32 is not exactly a "service". It's a program that is used to run
    lots of other programs. You'll need to look in Task Manager's Processes list
    to find the command line (use View\Show Columns to show that column -- a
    WONDERFUL new feature in Vista) used to call rundll32 in order to learn
    exactly what rundll32 is doing. There might be several instances of
    rundll32 there, so you'll have to diagnose from there.
