As most of you must know when trying connect to Multiplayer you will often be waiting up to 30 seconds for it too just tell you that you can not connect to the master servers.

There is a rather simple fix for this what will completely remove this delay.
Step 1 :- First of all you want to open notepad in administrator mode

Step 2 :- Now, in notepad click on 'File' and then 'Open...'
Step 3 :- Now browse too the following directory (you can do this manually or type in in the top bar) 'C:\Windows\System32\drivers\etc' and open the hosts file.

Step 4 :- Lastly you will need to add two new lines too this file:
0.0.0.0 nw2master.bioware.com
0.0.0.0 nwn2.master.gamespy.com
Do this and then go to 'File' then 'Save'

You will need to restart NWN2 for the changes too take effect. Now when you click on multiplayer there will be no delay.
I Hope this is helpful. I did this on windows 8 but it will work for Windows 7 (and maybe XP) if you have any trouble let me know.
