SSL configuration.

We have a Certificate Server with the Key Certificate installed on the on it and IIS is setup for secure comms ‘requiring a secure channel when accessing this resource’ and ‘require client certificates’ configured. When browsing to http:///certsrv/ from a clients browser to install a root CA certificate on the client, I get a message ‘HTTP Error 403.4 Forbidden: SSL required’.

I’m assuming that its telling me to use https:// as opposed to http:// but as I haven’t installed the client certificate yet I’m unable to select the cert to use and connect to the server in the first place! Its a catch 21 situation.

What am I doing wrong?
