If you are unable to connect to Battle.net, this issue can be caused by several different things.
If you are using Windows 2000/XP/Vista please first verify you are playing under an Administrator Account. Some user accounts can be restricted to save the information needed for the games connection and this can cause the connection problem. To find out which user accounts are marked as Administrator accounts, please see the instructions below:
-Click Start > Control Panel and look for an icon called User Accounts.
-Double click this and it should bring up a list of users on your computer.
-Find the user account that matches your user name and have a look in the group column, it may say administrator, power user or user. This is what type of account you are logged on with. If it says administrator you should be ok.
For Windows Vista, in order to set the game as Administrator Mode, please follow the steps below:
1. Right click on the game icon.
2. Select "Run as Administrator"
Also make sure you are not running any add-ons or modifications of any kind. These have also been known to cause connection issues. If such programs exist please completely remove them from your system. In some cases you may need to reinstall the game. If the issue continues please try each of the steps below.
Temporary Restrictions: (I did check the IP you've been posting from, and I don't see any restrictions, but still...)
Please try to connect to all four Battle.net Realms (USEast, USWest, Europe, and Asia). If only one Battle.net Realm is inaccessible to you, then it may just be a temporary connection problem or a temporary restriction. Battle.net access may be restricted for one of the following reasons:
* Spamming text in the chat channel (often associated with bots)
* Rapidly connecting/disconnecting to Battle.net (often associated with bots)
* Repeated attempts to use an invalid CD-Key or an incorrect Battle.net password
* Repeated use of third-party programs (hacks) - these include but are not limited to sending bad packets, flooding the server(s), and the use of hack programs
Battle.net Server List:
Your Realm or Gateway selections may have been altered in some way. This will prevent you from connecting to a Blizzard Entertainment Battle.net server. For instructions on restoring the correct server list for Diablo II, Warcraft II, and StarCraft, please go to this page ("http://us.blizzard.com/support/article/21138").
Internet connection notes:
Firewalls, Routers, and Internet Connection Sharing
* If you are using any type of firewall, router, or you are sharing your internet connection between several computers, you may need to set your system up to allow access to Battle.net. For instructions on setting up your connection, please visit our Networking Help page - ("http://us.blizzard.com/support/article/21086").
I have tried running the game as admin, didnt work
I am the System Admin
I am not running any add-ons or mods
My game is patched all the way
I am not experiencing connection issues
I tried connecting to all Battlenet servers still doesn't work and the same error message pops up before i can even log on
I can log on to D2 and Warcraft III Battlenet servers just not this one.
My connection is fine.
Firewalls are down.
I don't have any apps running while i run the game.
I have tried to re-install but the problem still exists.
I have read somewhere that it maybe because im lacking Mircosoft TrueType Core fonts seeing how i had Font issues where alot of them where deleted after deleting Fire Fox

Running a trace route may help identify where the connection problems are occurring. This does not imply that your internet connection is having problems but this does help us test the connection from your computer to our servers and every "hop" in between. Using this program can help determine what location the data you are sending is running into a problem.
Steps to run the Trace Route command:
Windows Vista Users:
1) Click Start and in the "Start Search" field type "command" or "cmd".
2) The search should find the cmd.exe program. Please right click on that program and select "Run as Administrator" to load up the command window.
3) In the command window, type tracert realm.battle.net > C:\tracert.txt and press the Enter key. Note that realm should be replaced by the site you are having problems reaching (Asia, Europe, USEast, USWest) example: tracert USWEST.battle.net > C:\tracert.txt. A file will be created on your C: drive called tracert.txt that contains your trace route information.
4) Type exit and press the Enter key to close the command window.
