Connection problems in all applications except Safari

Hi there,

I hope this is the appropriate forum for this question. I am completely new to OSX, so please be patient.

I am trying to fix a problem for a colleague of mine.
His Macbook Pro running Snow Leopard cannot connect to the Internet with programs other than Safari. He (and I) has tried nearly all we can think of:

Different browsers (Firefox,Opera and Chrome), different IM-Clients (iChat, ICQ),
pinging Google (does not work), wireless connections as well as ethernet (in different networks). A portscan shows only 80 as open, though there are several other open orts on this particular router.

Connection settings have DHCP enabled. IPv6 is disabled, DNS server is set to the public Google DNS.

As stated: Safari works fine, nothing else does.
Any ideas? :Smirk:
