CEM clients are not using HTTPS to connect to SMP

Hi

I am trying to set up CEM and am having difficulty getting clients to connect to the SMP using HTTPS. I have a targeted client config policy which configures the client to use https://server.abc.local/Altiris to connect to the SMP and the targetted machines have been removed from the general client configuraiton policy. The default web site on the SMP has it SSL set to require SSL and ignore client certificates (The Altiris web site doesn't have this set though). I can access the console using https.

But the clients continue to connect to the SMP via HTTP regardless of what I seem to do.... What have I missed?

Thanks in advance

Steve
