Not many people host that map, I do it 1-8 times a day tho I use europe bnet mainserver.
Most people cnt host and I found out 4 pionts to get sure they can:
1st Reason:
Youre Windows XP software firerwall. This useless and automaticaly activated firerwall blocks all servers you open to "protect" you. It is useless cause even Ican get past it.
1st Solution:
Just deactivate it in youre system control and get a Softwarefirerwall like Zonealarm or a similar program, just search one via google.
2nd Reason:
Youre Software firerwall blocks the server option of the wc3.exe or wcIII.exe application, or does not fint it and autoblocks it.
2nd Solution:
Simply go into youre softwarefirerwalls application-option-menue and search the wc3 or wcIII.exe application. Once you have found it simply change it to allow server. If it simply doesn t finds the application reinstal the softwarefirerwall, or mail to the support adress of the company which produced youre software firerwall.
3rd Reason:
Youve got a router. Many people don t know it cause the technician or the uncle or whoever installed the internect accses in theire house or simmply have no clue about soft and hardware. Everey router has a hardware firerwall which simply blocks every port but the ports which are usualy used, like the one Windows Internet Explorer is using or Outlook Express.
3d Solution:
If not yet installed download and install a routercontrolprogramm from the company which made youre router, search via google.
When it is installed tell it to unlock the port 6112, thats the port which is put standart in youre warcraft 3 gameplay options menue for people to conect to youre server. If you can t open that port simply change the port from 6112 to a yet opened port in youre gameplay options menue.
If you don t know, if youre having a router or a modem, get youre uncle a technician or who ever has a greater knowledge about networktechnique. Show that person this post and it should know what t do.
4th Reason:
Som provider block all unusual ports to protect theire customers and youre having such a provider.
4th solution:
Write an email to youre provider to open a certain or some certain ports.
If all theese problems are exterminated and you still can t host you have bad luck. backround firerwall or a bad script in one or a failure in windows or what ever is blocking the port/application.
I am finished with my Computerlatin and can t help youn anny further just give it up.
Or you are hosting a totaly noob and unliked game like dota or candywar and ofcourse noone joins a noob game.
