Safari and Google
He is a relatively recent convert from Windoze to a Leopard running iMac and I am fairly certain that all relevant updates have been applied.
Recently (a matter of a fortnight or so, I believe) he has been unable to access either google.com or google.co.uk, receiving the message, for example: +Safari can’t open the page “ http://www.google.com/” because Safari can’t connect to the server “www.google.com”+.
His Safari can connect to all other websites as normal and his Firefox can connect to all websites including google.com and google.co.uk
I, although with a different ISP and running Snow Leopard on an i7 iMac, can connect to google just fine.
We've deleted Safari's Google cookies, emptied Safari's cache, reset Safari, deleted the plist and run Repair Permissions.
He does not run Little Snitch or anything similar so I can't see any access "rule" that might have been unknowingly changed and I have run out of ideas as to where to look or what to do next.
If there is unsupplied information which might help track this down, I'll do my best to find and post it.
Thanks in advance.
27" quad-core i7 iMac, 1TB HD, 4GB RAM, Mac OS X (10.6.6), Also G4 eMac and G4 Tower
