Perfect timing, I was just about to send you an update on this:

I talked to Trevor about this, and he suggested the best thing to do for IIS would be the following (Trevor, please double-check I got this right):
If there is an EKU, and it has serverauth, display it in the list to pick web server certs from
If no EKU, look at basic constraints:
    * If we do not have basic constraints, do display it in the list to pick web server certs from
    * If we do have basic constraints with Subject Type =CA, don't display it in the list to pick web server certs from (this will filter out CA certs)
    * If we do have basic constraints with SubectType !=CA, do display it in the list to pick web server certs from 
*/

/*
===== Opened by kshenoy on 11/13/2000 02:26PM =====
Add Existing certificate option in "Web Server Certificate Request wizard"  should not list CA certificates in the filter
but only End entity certificates with "Server Authentication" EKU

Since CA certificates by default have all the EKUs the filter will list CA certificates apart from 
end entity certificates with "Server Auth" EKU.

In order to check if a given certificate is a CA or end entity you can look at the Basic Constraints 
extension of the certificate if present. This will be present in CA certificates and set to SubjectType=CA.
If present in end entity certificates it will be set to "ServerAuth"
