    Hi Ray,

    Thanks for your posting back.

    As for the current situation, I suggest you go through all the steps in the
    following article:

    833401 How to configure RPC over HTTP in Exchange Server 2003:
    http://support.microsoft.com/?id=833401

    Especially check the registry key for ports configuration.

    I am looking forward to hearing from you. Have a nice day!

    Thanks & Regards

         Alan,
         Sorry for the delayed response, I was away in Europe last week.
         
         I have the IIS virtual directories set up as you suggested which
    corresponds
         to the original directions I followed here
         http://support.microsoft.com/?id=833401 .
         
         I am still getting the same result.
         
         Ray
