Rien de particulier dans le log serveur, le voici :
//Example config. Note that everything behind // is ignored by the 
game
//Try to keep cvar-values as short as possible. Otherwise you might 
get "info string length exceeded" errors on your server
//*** Administrator Info, shows in some gamebrowsers ***
sets " Admin" "adminname" //Uses a space in front so it shows up at 
the top of the properties list
sets " Email" "
xxx@xxx.xxx"
//*** Server Name and Daily Message ***
set sv_hostname "Pit Serveur" //Your servername here
set g_motd "Urban Terror" //Your message of the day here, it is 
displayed while connecting

when the game is joined
//*** General Game Settings ***
set sv_maxclients "12" //max clientslots available on the server, 
using more than 16 is not advised. It can cause lag and most maps are 
not built for it. Going over 24 can cause nasty bugs.

game. Other clients are forced to spectate. 0=all
set sv_privateClients "0" //Amount of private slots. This amount of

sets sv_dlURL "urbanterror.net" //Sets the address for 
auto-downloading. Auto-download only works on ioUrbanTerror-clients, 
not quake3-clients. The client will try to download 
<sv_dlURL>/q3ut4/mapname.pk3. So if your server is running ut4_coolmap 
and sv_dlURL is set to 'yoursite.com/maps', make sure the maps is 
hosted at 
http://www.yoursite.com/maps/q3ut4/ut4_coolmap.pk3. Leaving 
this set 'urbanterror.net' will make it use a map mirror with the most 
common maps on it. If you got your own hosting, please us that though, 
to save bandwith.

_________voila
pour le lancer j'ai fait un .bat avec les lignes de commandes de ton tuto.. :
cd C:Program filesUrbanTerror
ioUrTded.exe +set dedicated 2 +net_ip xx.xx.xxx.xx +exec server.cfg
voilou...
Mais je pense vraiment à un bug ?
