this problem started yesterday:
only some of my programs are working on the internet. Safari, versiontracker, itunes and software update are not connected, but firefox, entourage and skype are. I've used the network diagnostics and internet connection assistant and that shows I am connected.
Firefox, Skype, Mail and Entourage work fine.
I have restarted a few times.
I have a 17in Mac Powerbook and am running OS 10.4.11
The other MACs in the office are working fine. They can connect via itunes, Safari, software update and versiontrackerPro, but I cannot.
I can get to www.versiontracker.com
but my versiontrackerPro will not connect.
I tried connecting via Safari to http://220.127.116.11/
and got the message that Safari could not connect because it could not find the server.
I downloaded the DNSchanger removal tool and I do NOT have that trojan horse.
