Issue: SSL Binding Lost in IIS 7.0 & 7.5 on Web Admin Server


Users cannot access  Web Admin Console over https.  After checking the bindings in IIS the certificate setting is lost/deleted for the https binding on port 433


The SSL binding for the website has been deleted and not replaced, or has been deleted and replaced with invalid certificate info.  The problem occurs because of a legacy SSL certificate hash property interfering with the current SSL binding, resulting in the correct binding being deleted.


Locate the following property in the <CustomMetaData> section of the applicationHost.config file, and delete it:

<key path="LM/W3SVC/X">

     <property id="5506" dataType="Binary" userType="1" attributes="None" value="oXiHOzFAMOF0YxIuI7soWvDFEzg=" />



This property is a legacy feature from Internet Information Services (IIS) 6.0 and is no longer needed.
