Thanks... This is what I get:

-> irc.makaiwell.com NICK [RO]M1Rc34
-> irc.makaiwell.com USER _RO_M1Rc34 "mirciulik" "irc.makaiwell.com" :Mirciulikkk
<- :starship.tx.us.makaiwell.com NOTICE Auth :*** Looking up your hostname...
<- :starship.tx.us.makaiwell.com NOTICE Auth :*** Could not resolve your hostname: Domain name not found; using your IP address (<my ip>) instead.

I don't use any firewall... Only windows default firewall...

Thank you and please help me out since it is very annoying
