Cannot connect to PI OPC Server remotely

Hi,  We are updating our PI interface server to 2019 and installed PI-OPC-DA-Server_2018-(x64).  We have configured the local user accounts and modified the DCom settings to the same as what the old interface server.  Locally when you run the PI OPC test client it works fine and you can browse the DA server.   However if you try from remote clients you can see the prog id and connect on the server but if you click the status button it throws a "the parameter is incorrect" message up.  Now this is using an RSlinx OPC client on one of the test clients and I ran the PI opc client as well.  We cannot connect.  We've been through the usual cast of characters, local accounts, Dcomcnfg, OPCENUM, etc.

 

Any thoughts on this would be greatly appreciated.  We've been using OPC for years and this is the first time I've seen this type of problem.   

 

Thanks,

 

Harry.
