    shared configuration - authcert.dll failed to load

    Hi,

    I'm having a problem with a shared WWW farm using the new  'shared configuration' feature of IIS7.

    The machines in the cluster all see new new virtualhosts and setting changes are reflected between hosts - however newly created application pools only work on the server they where created on, other servers show:

    The Module DLL C:\Windows\System32\inetsrv\authcert.dll failed to load.  The data is the error. 

     The data is: 0000007E    

    Any ideas as to where to look for the problem?

    Does C:\Windows\System32\inetsrv\authcert.dll exist?
    Do you have CertificateMappingAuthenticationModule(Client Certificate Mapping Authentication) installed?

    Thanks,
