Cannot connect to remote Mitsubishi OPC server using datasocket

[pincpanter]

I can read OPC items locally using datasocket, however if the client is in another PC I get error 1184 when I try to connect to an item. The datasocket Select URL does work, though.

Both computers are Windows 7 machines in the same workgroup sharing the same user/password.

I'm able to read items through the DSC OPC client (but I don't want to use DSC). This seems to indicate that security DCOM settings are good.

I know that there is plenty of documentation about remote OPC access and DCOM and I read most of the docs, by NI and other sources, to no avail; none of the docs are mentioning this specific error code. Any suggestions?

Well, it's typical... After two days of efforts, just 40 minutes after posting my question I got the solution in another thread of this forum.

The Remote Registry service must be running on the server machine.

Now I only need to carefully rewind some of the many settings I did, to find the minimum working condition.
