I was geting started with Opalis’ Remedy Integration Pack and found that I could not get a connection to my AR server.  I copied in the AR System DLLs into my Action Server and Clients per the IP instructions, but no go. 

After talking with Microsoft Support I obtained a yet-to-be documented fix when connecting to Remedy via port-mapper.  You will need to create a System Environment Variable called “ARTCPPORT” with the value of your Remedy TCP port.  I believe this is usually port 4190 by default.  This needs be created on any Opalis Action Server and Client making AR connections.
