to use the server on another machine from your machine, use the network 
tree control to open the machine, and select one of the OPC servers shown 
on that machine and press the Add Server>> button. The information for 
the remote OPC server is now stored in your local machine registry, and the 
server will appear in your BridgeVIEW servers list with the server name 
format of 

(

machine name)programID

. BridgeVIEW runs the server on 

the remote machine when you configure a tag to use that server. 

To remove one or more remote OPC server from the BridgeVIEW server 
list, select the servers and press the Remove Server(s) button. The servers 
will no longer appear in your BridgeVIEW server list.

You can also use the Windows utility 

dcomcnfg.exe

 to configure an OPC 

server to run on a remote machine rather than your local machine. In order 
to use 

dcomcnfg.exe

 to configure an OPC server on a remote machine, 

you must also have the server registered on your local machine.

To register an OPC server on your local machine, either install the server 
locally or run the server registration utility on your local machine. Then, 
launch 

dcomcnfg.exe

 and complete the following steps.

1.

Select the OPC server in the Applications list, under the Applications 
tab, and press the Properties button.

2.

Click the Location tab in the Properties dialog box. De-select 
the Run application on this machine checkbox and check the 
Run application on the following computer: checkbox. Enter the 
name of the machine or use the Browse button to select the remote 
machine. Press OK to close the Properties dialog box.

3.

Select the Default Properties tab and make sure that the Enable 
Distributed COM on this computer checkbox is checked. Also, 
set the Default Authentication Level to Connect, and set the 
Default Impersonation Level to Identify.

4.

Select the Default Security tab, and press the Edit Default… button. 
Make sure that the machine on which you plan to launch the OPC 
server is allowed to access your machine. This is necessary for the 
machine to call back the BridgeVIEW on your machine when 
supplying OPC values.
