Heidi:

Windows 10 Home or Pro? If Home then the connection to your network is being dropped. Upgrade to Pro. Otherwise;

Adagio versions?

Which AV are you using?

Put it on a different switch? You should only have one.

What are you using for a server? It shouldn't be necessary to turn off the firewall (and its not a good idea either).

This type of problem is very difficult to troubleshoot in a forum. You might want to call your Adagio consultant for assistance.
