Just updated to server to 0.9.11.1 and now I'm getting this... The CheckNetIsolation.exe command that the server tries to run (taken from the DEBUG log) requires UAC elevation. After I manually ran the command elevated the server seems to work again - but I'm still getting this error in the log file...

I see this error too now and my server is down. Clicked on CheckNetIsolation.exe and it did nothing.

You appear to have picked up a thread about a really old version of Plex Server. Can you please confirm which version you are running and on what platform?

Bringing this back from the “dead” as we still see this today with the very latest version of Plex. Just wondering how to get rid of this error. As a software “QA guy” for 25 years now, I detest seeing errors in the product logs!
