Hi,

I currently have Sage 50 2015 running on a Windows 2012 R2 server with several Windows clients connecting. In the past year, we have been able to open two company files on the server simultaneously with five or so users each. We have recently added another company file to the server's network share and can still open two simultaneously, but not three. We've tried different orders of opening the company files on client computers, and only two companies can be opened at once when accessing the server. 

In a network / server install of Sage 50, how many simultaneous companies can be open by clients from the server?
