Client won't talk to ATL Service

Answer 1

Do you select option "Add common header files for: ATL" in app MyClient ? This one work fine in my test.

Put service running at your user account (default is system account) for access at debugging IDE.

Good lock.

Answer 2

You may need to make additional registry entries under progid. I do not see where you are calling 'CoInitializeSecurity'

Microsoft supplies an example at http://msdn.microsoft.com/en-us/library/3ts2dxc8.aspx
