title: Cannot Start IIS on my PC: COM+ System Application: Access is Denied
body: <p>I'm trying to do some web development.  I cannot start IIS (I need to run some Web Services).</p>
  
  <p>As of about a month ago, the "COM+ System Application" service has started failing with this error:</p>
  
  <blockquote>
    <p>The COM+ System Application service
    failed to start due to the following
    error:  Access is denied.</p>
  </blockquote>
  
  <p>DCOM also logs an error in the event log:</p>
  
  <blockquote>
    <p>DCOM got error "Access is denied. "
    attempting to start the service
    COMSysApp with arguments "" in order
    to run the server:
    {ECABAFBC-7F19-11D2-978E-0000F8757E2A}</p>
  </blockquote>
  
  <p>When I start IIS and the WWW service, everthing seems to work until I hit port 80 on my machine at which time the IIS/WWW services both crash unexpectedly:</p>
  
  <blockquote>
    <p>The World Wide Web Publishing service
    terminated unexpectedly.  It has done
    this 1 time(s).</p>
  </blockquote>
  
  <p>The following event is placed in the application log as well:</p>
  
  <blockquote>
    <p>The run-time environment has detected
    an inconsistency in its internal
    state. This indicates a potential
    instability in the process that could
    be caused by the custom components
    running in the COM+ application, the
    components they make use of, or other
    factors. Error in
    f:\xpsp3\com\com1x\src\comsvcs\package\cpackage.cpp(1184),
    hr = 80070005: InitEventCollector
    failed</p>
  </blockquote>
  
  <p>I have searched google until my fingers are numb.  I've searched this site to no avail as well.</p>
  
  <p>I have tried:</p>
  
  <ul>
  <li>running the COM+ System Application service as an administrator.</li>
  <li>reinstalling SP3 for XP</li>
  <li>giving the "SERVICE" account full control to %SYSTEMROOT%\Registration</li>
  <li>removing XP Security hotfixes installed about the time it stopped working</li>
  <li>I've removed and reinstalled COM+ (it's possible, check google)</li>
  </ul>
  
  <p>Any insight on the COM+ subsystem, it's files and settings or just how it operates would be greatly appreciated.</p>
  
  <p>I need to get this problem resolved so I can get back to work.</p>
