  • Try following before re-install IIS if you can't find Distributed Transaction Coordinator in your Services console.

    Launch command prompt and run the following command.
    >msdtc -install
    >net start msdtc

    Then try re-install IIS. This problem is related to the previous topic.

  • I assume you diabled Distributed Transaction Coordinator Service which you can check in the Services console in the adminitrative tools.

    Try running Distributed Transaction Coordinator, uninstall/install IIS, and access to your asp page.

  • Unfortunately, this didn't work for me and I've been around and around on this for most of the week.  At this point I'm simply going in circles.

    Here's what I'm seeing:

    I am serving web pages on XP/SP3 using IIS 5.1. 

      * Plain text/HTML pages work fine - they are viewable in a browser.

      * ASP pages cause an HTTP 500 error and the event log shows:

    Event Type: Warning
    Event Source: W3SVC
    Event Category: None
    Event ID: 36
    Date:  5/3/2012
    Time:  10:20:38 AM
    User:  N/A
    Computer: XXXXXXXXX
    Description:
    The server failed to load application '/LM/W3SVC/1/Root'.  The error was 'Class not registered
    '.

    Searching the web points to MSDTC as the culprit, or more specifically COM+.  I've uninstalled, then deleted the registry keys, then reinstalled each and both together.  COM+ gives the following error when being reinstalled:

    -----

    Subcomponent COM+ raised an exception while processing the OC_ABOUT_TO_COMMIT_QUEUE setup message. 

    d:\xpsp\com\com1x\src\complussetup\csetuputil.cpp Line 4437  

    Error code 0x8007041c

    -----

    DTC simply will not start.

    I'm beginning to think at this point that there may be bad spots on the hard disk or the system image itself may be corrupted, but I'm sure that's just frustration speaking.  ANY ideas would be tremendously helpful at this point.  I'm completely at a loss as to how to proceed.
