Since a few weeks, the 3s OPC server (opcconfig.exe v22.214.171.124) refuses to get discovered on my devbox. I use codesys 2.3 runtimes in combination with Classic OPC, thus UA is no option. As a client I use Matrikon OPC explorer for test purposes. It uses OPCEnum.exe to browse the system. OPCEnum does not return any installed servers.
My box is a Win 10 Pro installation with the windows newest patches/_ updates.
Has anybody got a workaround?
I would give this a try:
mmc comexp.msc /32

The cause was the winter Service pack for W10 (jan 2018)
Installing the latest service pack will autoresolve this issue.
