> [!NOTE]
> Note:
> 
> OPC Classic standard specifications rely on **Microsoft's COM and DCOM** to exchange data between automation hardware and software. **DCOM** needs to be configured properly in order to allow users to establish remote communications between their OPC client and server components.
> 
> 
> 
> In this document, we describe the necessary steps to get DCOM working properly under Windows in a Workgroup configuration, specifical adjustments will be required depending on the Windows version.
