Hi Dave,
Sounds like you have internet back and are using your own local server, not the cloud.
Do you mean that a peer-to-peer W10 computer acting as a server won't even start and go to its desktop?
Or that your W10 server starts, but won't load AC as a database server for anyone to use?
Or that AC loads on your server, but no one including the server can open an AC session?
Error message?
Cheers,
Carl Fogel
