Hello ,


Using windows 2003 enter edition having exchange 2007 client access server running on it. SSl comes by default in exchange 2007

i was trying to install a client certificate using certificate services. Installed enterprise root CA on DC . In the client access server, If i go to the IIS manager --> directory security tab and clear the checkbox that says " require client certificate" it works when i connect to owa, exchange virual directories.


  From what i understood we need a browser certificate .


Have referred some docs on certificate services


BUT when i go to http://localhost/certsrv it comes up with 2 options

1) submit user certifiacte

or submit and advanced client certificate


Advanced Certificate Request  says:

The policy of the CA determines the types of certificates you can request. Click one of the following options to:  

1)Create and submit a request to this CA.
2)Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64-encoded PKCS #7 file.
3)Request a certificate for a smart card on behalf of another user by using the smart card certificate enrollment station.
Note: You must have an enrollment agent certificate to submit a request on behalf of another user. 


From http://support.microsoft.com/kb/315588/en-us

The server side is alreday there . so i think we have to go to the client certifiacte side. The following is extracted from that doc.

What it says in the doc is not coming up. i dont see an option for browser certificate at all.
