Hi, Thaltanium,

Normally, being unable to connect to a single realm indicates an IP restriction. However, assuming you're posting from the same connection that you use for playing, I don't show any restrictions.

Sixen is correct in that you need to open up the firewall ports. Once you've configured your firewall, flush your DNS:

For XP:

1. Click Start, then Run.
2. Type in CMD
3. When the command prompt comes up type in the following in succession, all without the quotes:

"ipconfig /release" press Return
"ipconfig /renew" press Return
"ipconfig /flushdns" press Return

4. Close the DOS window and try WoW.

For Vista:

1. Click Start, then Run.
2. Type in CMD. When you see the command prompt come up, right-click and choose "Run as Administrator."
3. When the window comes up, type in the following in succession, all without the quotes:

"ipconfig /release" press Return
"ipconfig /renew" press Return
"ipconfig /flushdns" press Return

4. Close the DOS window and try WoW.

For Mac OS X:

1. Navigate to /Applications/Utilities/ and launch Terminal.
2. Copy/Paste the following:
For Leopard (10.5):
dscacheutil -flushcache
For Tiger (10.4) and Panther (10.3):
lookupd -flushcache
3. Press return.

Hi, Oktomatik2,

Your connection has been temporarily restricted from Battle.net. This restriction is realm-specific and can last up to 2 weeks.

It can happen for any of the following reasons:
- Using an invalid CD key
- Rapidly connecting and disconnecting to Battle.net
- Creating or joining numerous games within a short time period such as "Magic finding" or "Baal runs"
- By the use of "add-on programs"
- Chat channel abuse
- Failed login attempts
- In game latency caused by excessive spell effects

We are unable to lift these restrictions early or tell exactly why the restriction was placed on your connection.
