To have a dedicated server download this: http://www.filefront.com/846108/t2servers.zip

After you have the server tools you can run your server, but first you need to configure the gm.cfg file.

For Example:

;;; SERVER OPTIONS
;;;

;;; HOSTPORT
;;; The port that the GameManager is listening on.
;;; Values: A port number (it should be between 12880 and 12889 inclusive).
;;; Default: 12888.
HostPort=12880

;;; HOSTNAME
;;; The name of the game server.  This is the name that will show up in
;;; GameSpy as the name of the server.
;;; Values: Any string.
;;; Default: None.
HostName=Server Name

;;; SERVERIP
;;; The IP address of the RTime server.  Typically, this will be the same as
;;; the IP address of the GameManager, so if it is left undefined, the GameManager's
;;; IP address will be used.  However, if the RTime server is running at a
;;; different IP address (e.g., on a different machine), it must be specified here.
;;; Values: An IP address.
;;; Default: None.
;ServerIP=127.0.0.1

;;; SERVERPORT
;;; The port that the RTime server is waiting for connections on.
;;; Values: A port number.
;;; Default: 12800.
;ServerPort=12800

;;; GAMETYPE
;;; The type of game being hosted.
;;; Values: Rok Match, Team Rok Match, CTF, Arena, Team Arena.
GameType=Rok Match

;;; LEVELSET
;;; The level set being used (.LSM file).  The name should NOT include
;;; the extension.  The GameManager will look for the file in the
;;; Data sub-directory of the directory that the GameManager was run from.
;;; For example, if "Levels" is specified then then the actual path to the
;;; level set file will be "data/Levels.lsm" relative to the directory where
;;; the GameManager was run.
;;; Values: A level set file name without the .LSM extension.
;;; Default: None.
LevelSet=Rok Match Levels

;;; LEVELS
;;; A space separated list of levels to play within the level set (in the
;;; order that they should be played).
;;; Values: The value must contain a space separated list of level numbers.
;;; The levels are zero indexed; i.e., the first level is level number 0.
;;; For example, to play the second, first then fourth level, you would specify:
;;; Levels=1 0 3.  If this key is left undefined, all the levels within
;;; the level set will be played in order.  Use the -listlevels command line
;;; parameter to get a list of all the levels in a level set.  For example:
;;; gm_win32.exe -listlevels "Arena Levels.lsm"
;;; Default: Play all levels in order.

;;; would yield "Bob caught a bullet from Jim." if Jim had just killed Bob
;;; with the Pistol.  Note that a construction like "KillXYZ=%s killed %s." is
;;; doomed since the player killed ALWAYS comes first.  Suicide strings contain
;;; only one %s, and local strings contain no %s.

You can edit the Host port (if you want to start more server then change in each gm.cfg file); Server's name; Game type; Levels set; Levels; Max Players; Number of teams; Teams; Arena weapons; Arena Health

The last 3 line is extra, but if you want to change speed and other, then there you can write after the worldid Speed...

If you want to play Arena with Rok Match levels you need a special gm_win32 file - that can be found on the kBg site.
