The connections limit counter counts all types of connections (connections to physical desktop, virtual desktops, custom sessions, sessions which have been reconnected, sessions connected to other user's virtual desktop). The value specified as limit cannot be higher than the maximum number of connections or virtual desktops allowed in the license file (server.lic and/or node.lic) in the 'Connections' and 'Virtual Desktops' field respectively. Limits on the number of virtual desktops and/or connections can be set in two ways: (i) in the server configuration or if the server supports profiles, (ii) via profile rules.

For example, a NoMachine Workstation allows up to four concurrent virtual desktops, this overrides whichever other value set in the server configuration.

However, number of virtual desktops depends on the license. To set unlimited, set the key to 0 or comment it out by pre-pending a #, e.g. 7.6.2, number of virtual desktops and connections set globally or on a per-user basis are no longer limited by default to 20 and are unlimited, i.e.
