This is fairly common with RSLinx. Please try some other OPC client, from the same machine. I expect that you will get the same error.

In such case, the reason is in RSLinx - it requires a different product or license for remote OPC connections.

I am using the Easy OPC-DA (COM) Demo Application to try to get data from a Remote RSLinx server. The application finds the RSLinx Remote OPC Server but when I try to read a tag I get the error:
