There is no Windows imposed limit on the number of users. Even if you run on a server. Except of course if you deploy a client app on the server and users access it using RDP. Then each user would need a CAL, but otherwise , no restrictions.
Do not run FB server on a serer that is a domain controller. There is sufficient empirical proof that this is not good… From: firebird-support@yahoogroups.com [mailto:firebird-support@yahoogroups.com] Sent: 30 October 2014 06:08 PM To: firebird-support@yahoogroups.com Subject: [firebird-support] FB server installation and concurrent users limits on Windows Server Hi I know that FB as software doesnt have any limit to the users that can access the engine. I am wondering if is there any “access limit” imposed from a windows system server (like the latest 2008/2012) that will require to buy extra licenses I suppose that If I will install FB server on a window “client machine” for a small network group I will have no limitation about users that can connet to the machine and then to FB engine What if I will install the engine on a Windows 2012 RX server? I already know that the license comes with possibility to validate 5 users simultaneously accessing the server and you have to buy extra CAL If I will not use a DOMAIN and the windows system control about users accessing FB engine would I have no limitation about the number of CLIENTS that will access the FB server engine?
