The server is an optional component complementing Fomine Software instant messaging solution. Winpopup LAN Messenger can work with or without a dedicated server, but several functions can not be resolved in server-less architecture. If Winpopup Server is installed on the network, all Winpopup LAN Messenger and OfficePopup clients will discover it automatically, and route all communications through the server. Winpopup Server supports the following functions:
* Authorization
* Offline message delivery
* Communication in complex networks containing multiple subnets
