Why can't I connect to my DSC OPC server from a remote client PC?

[markwysong]

I have two PCs, both with LabVIEW 7 express and the DSC module. One PC is the host, running NI-DAQ 7.1 and is used for the OPC server. The application runs perfect on the host machine. However, on the client PC, when I try to connect to the OPC server on the client, it won't connect.

What's worse is that it DID connect for a day, then quit. I've tried setting the DCOM to allow the client to run the OPC server, but still no connection. I'm at a loss as to why it won't work.

I've set up the host machine's C drive as a shared drive on the network, and I can see and connect to it from the client, so I know it's on the network. Any ideas?!?

Thanks,

Mark

Mark,
You should probably consider posting the question in the LabVIEW Datalogging and Supervisory Control category. You will probably get a better response there.
