Browser connection URL
Typically, the browser connection (user interface) may look like:
http://yourserver/I4/
As you can see, the URL starts with the address of your server (http://yourserver), to which gets added the name of your Web application.
For the Administrative modules, after the name of the Web application in i4 add /admin, and for older browser versions add /int:
http://yourserver/i4/admin or http://yourserver/GN4/int.
GN4 client connection URL
In GN4 versions 2.1 and newer, the GN4 client connection URL is the same as the browser URL. Since the version 2.4 it is recommended to use the i4 web application, and not the GN4 one, e.g. http://yourserver/I4/.
In GN4 versions 2.0 and older, the GN4 client connection URL is similar to the browser URL, with the addition of AdminSrv.asmx, e.g.: http://yourserver/GN4/AdminSrv.asmx
