Can't start IIS Admin Service RRS feed

  • Question

  • User1595901063 posted

    I am unable to start the IIS Admin service.  I would simply reinstall IIS but I have SCCM installed, and WSUS on the same server.  This is what happens when I try to start the service:

     Windows could not start the IIS Admin Service on Local Computer.  For more information, review the System Event Log.  If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code -2146893818.

    When I revew the event log this is what I see:

    Log Name:      System
    Source:        Service Control Manager
    Date:          11/1/2011 2:41:58 PM

    Task Category: None
    Level:         Error
    Keywords:      Classic
    User:          N/A

    The IIS Admin Service service terminated with service-specific error 2148073478 (0x80090006).
    Event Xml:

    The WWW service starts normally and I am able to access the web sites associated to the server.  I have tried restoring the c23 file for the keys but the problem persists.  Any help is greatly appreciated.

    IIS Admin Service is not required in IIS 7 for as long as you are not using IIS Metabase compatibility feature or FTP 6 publishing services. I assume you encounter an issue about IIS6 in Windows Server 2003.

    Generally, this issue caused by MachineKey can’t be found or doesn’t match. Since you said restoring the c23 file does not work, you may need to restore your MetaBase.xml file which is located at"%systemroot%\System32\inetsrv" .

    Please check the following articles to see if it address this issue.

    IIS6: "Supposed" Metabase Corruption

    I have followed those articles with no luck.  I believe the 2nd one is for II6 only.  If I restore the c23 file to one of those directories it will automatically appear in the other.

    I have restored the MetaBase.xml file as well and it still refuses to start.  Another problem I had noticed is when looking in the IIS console and using the "Features View" causes my console to freeze and return this error:

    {0} Home
    There was an error while performing this operation
    Server execution failed

    If I change to content view I am able to view the site content.

    I am using Server 2008 R2 x64 with IIS 7.

    I suggest create a post at the System Center Configuration Manager ( SCCM) Forums

     http://social.technet.microsoft.com/Forums/en-US/category/configurationmanager and let the Experts help with

    the error from the log.

    After correcting that part of the problems update this thread.

    IISAdmin service is not essential for IIS 7. However it is present for backward compatibility only.

    the error code that is being logged during the service startup failure suggests that the machinekey is corrupted:
    C:\>err 0x80090006
    # for hex 0x80090006 / decimal -2146
    # Invalid Signature.
    # 1 matches found for "0x80090006"

    Delete the C23 key and then try re-installing the IIS 6 metabase compatibility feature. Also check the permissions on the Machinekeys folder.

    For windows Server 2008, the folder location is this: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys
