My firewall keeps telling me I am being attacked!

Attack Type: NetBIOS Browsing (WTF is that??)
Source of last attack: 210.214.209.46

I looked it up... it's this website, but it doesn't load.

Domain Name: SATYAM-INFOWAY.COM
Name Server: SDNS.SATYAM.NET.IN
Name Server: PDNS.SATYAM.NET.IN


Anyone know who this is? Why are they attacking me?
