I can't work this one out.
I have a PC where Firefox, Safari and Subversion (Tortoise) can happily access the Internet and Outlook can pick up email but IE6 and IE7 both say they can't find a DNS server and Dreamweaver says it can't resolve a domain name. I can live without IE7 but I rather like Dreamweaver.
I've flushed caches, replaced network cards, reinstalled IE7, used OpenDNS and everything else that's been recommended to me but I'm still in the same place. Before I throw the whole PC away, can any of you experts suggest what this could be?
