Just wondering if the fine folks at Opto22 have checked to see if the Microsoft DCOM Hardening patch (CVE-2021-26414) will have any adverse affects to OptoOPCServer connectivity? I have been getting notifications from other vendors (Rockwell Automation especially) indicating issues with certain primary applications in their ecosystem not working correctly with the hardening patch activated. I suspect that the OPCServer is probably not widely used in the community, but for me it is fairly significant as this is the route we have been using for years to get Opto22 processor data into our PI Historian. Yes, there are more modern ways to do this, like with API calls and JSON parsing, but for us users that still have a large base of SNAP processors and I/O out there, OptoOPCServer is also still the best option for allowing multiple PACDisplay clients to connect to individual processors. I searched a little through the forums and didn’t see this question addressed previously, so I thought I would put it out there and see if this may be an issue waiting to bite me. Thanks in advance for any responses.
