I recently upgraded my computer from XP to Vista Home Premium. When i open WOW i connect through Blizzards servers. Even tho my realmlist it set to my server. It still connects to Blizzards server even if i delete the realmlist and no there aren't any other realmlists in the WOW folder. I also deleted my cache folder. I have reinstalled WOW over 3 times.
Oh ya i could connect to my server before the upgrade and my friend has Vista and he can connect to my server.
+Rep If u can figure this one out.
