title: WCF Client Certificate Authentication, The SSL settings for the service 'SslRequireCert' does not match those of the IIS 'Ssl, SslNegotiateCert'
body: <p>I have a website that is going to be called from some clients which will be authenticating with client certificates and others which will not be, because of this i have to have iis settings for client certificate set to allow.  This works fine on a windows 7 professional however when i try to run this on a virtual server setup with windows 7 i get the following error</p>
  
  <p>The SSL settings for the service 'SslRequireCert' does not match those of the IIS 'Ssl, SslNegotiateCert'</p>
  
  <p>All iis settings seem to be the same between the two environments</p>
