Pleased to hear that your problems are gone master.00. I am still without any solution to this and it is surely driving me mad. I have the workaround to get to google by using one of their IP numbers directly but it seems more and more sites are getting in the zone of not getting pass the DNS and getting their IP numbers is always a nuisance and sometimes also not possible.
I have tried all sorts of solutions, looked at host files, cleared all caches, turned off IPv6 etc etc. but still nothing that helps.
My first thought was that I had got this flash trojan (since I am a developer and among other things also uses Flex 4.6 I thought that I by mistake had installed some dirty flash version) but investigation shows me I am clean of that.
I can not really remember what could have been installed when this problem first occured to me. I am not thinking if this may be caused by some of the many VPN tools I am using (I am really desperate for a solution and trying to grab every little thing I can).
If I haven't already stated that, I am using OSX 10.6.8 (switching to Lion is not an option since I need to be able to have some developer tools to support older systems). The error I get in Safari is the following
Safari can't open the page.
Safari can't open the page "http://www.youtube.com/" because the server
unexpectedly dropped the connection. This sometimes occurs when the server
is busy. Wait for a few minutes, and then try again.
No error is seen in the error console and the loading of the site (in this case youtube.com) can be seen in the attached screen shot.
The error I get in FF is
The connection was reset
The connection to the server was reset while the page was loading.
The site could be temporarily unavailable or too busy. Try again in a few
moments.
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
Still some sites are ok and mac-forums is one so I am still above the surface
If anyone has anything, please let me know!!!
