Generic Host Process for Win32 Authorized or Blocked

I just Installed Look 'n' Stop 2.04p2 on a fresh Windows XP with SP1 install.
I use a PPPOE connection thru a network card to a "modem".
Network Card has been setup with no ip stack or other protocol.
ISP connection is PPPOE with only the Internet Protocol (TCP/IP) and Look 'n' Stop Driver enabled.
TCP/IP is configured to get IP and DNS Automaticaly. Netbios over TCP/IP is disabled.
When connecting "Generic Host Process for Win32" try to connect.
Should I authorize It ?
If I chose to block it, I can't resolve addresses, so browsing is not possible for exemple.

Thanks in advance for your replies.

 

DNS Resolving is done through “Generic Host Process for Win32 Services”, blocking this from Connecting rights will prevent you from communicating to the Outside... Basically yes authorize it to connect…
