Network Browser Error When Browsing for OPC Server on Windows 2000 MachinesPrimary Software: Measurement Studio>>Professional Edition (Base Package)Primary Software Version: 8.0 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I am trying to browse to my OPC server using the dialog that launches with SelectUrl Dialog in Microsoft Visual C++, Visual C# or Visual Basic .NET. I always get the following error dialog (pictured below also): NI Network Browser Error: error code - 0x80004002 No such interface supported An OPC Interface could not be found Ensure that the latest opcproxy.dll is installed and that it has been registered. How do I fix this? Solution: The Datasocket component used to enumerate the OPC servers available on the system is not being correctly registered on Windows 2000 systems. To use Datasocket as an OPC client, you need to manually register opcproxy.dll. To manually register opcproxy.dll, run the following command:C:\WINNT\system32\regsvr32.exe C:\WINNT\system32\opcproxy.dllNote: The path to the system32 folder on your machine might be different. If the previous command does not work, search your hard drive for regsvr32.exe and opcproxy.dll and correct the paths.Related Links: DeveloperZone Tutorial: Developing Industrial Automation Applications using Visual Basic .NET and OPC Attachments:
