I can't enter the battlenet and I tried to solve this problem according to http://us.blizzard.com/support/article.xml?articleId=21139&rhtml=true

I managed to connect to Europe and USeast [ that I hardly enter ] . But I couldn't open asia and US west server when I typed

telnet asia.battle.net 6112 all figures are removed it's good so far but after this whatever I do,

instead of "This is a Battle.net server Your IP address is [ ] connection to host lost"

just "C:\Documents and Settings/Wonseok Joo" turns up and nothing happens at all

Its obviously a problem with your internet, maybe a firewall setting is blocking bnet, or your ISP suddenly hates bnet.

Change internet or connection hardware recently?
