Certain (variable) websites won't open in Safari / Google Chrome

Hello,
Can you help a relatively new owner of a shiny macbook pro?
OS 10.6.5

Safari won't open certain sites. The following message appears.
Safari can't find the server. Safari can’t open the page “ http://www.whatever.com/” because Safari can’t find the server “www.whatever.com”.
Now I could find it earlier today, and if I refresh many times, sometimes eventually it will load up OK.

The same thing happens with Google Chrome.

I have reset Safari, used disk utility, no go.
This has been happening on and off since I bought this macbook - around 2 months ago.
Can anyone assist?
Thanks!
Lucy

Macbook Pro, Mac OS X (10.6.5)

Heya,

Sounds like (i'm nearly certain) an issue with your router OR Intenet connection.

Can you check the 'Console' to see if you are getting time outs with your wireless connection?

Do you ever notice the little wireless connection drops (the signal bars near the clock on the top left of the screen?

Finally does this happen on other PC's/iPods/devices on the wireless network?


Can you try connecting to your router with an ethernet cable and see if the problem persists? (to rule out your ISP being the issue)

Regards,
John

I think I've found the answer. It is at least continuing to work for meUser uploaded file It seems that it was Peer Guardian. Even when it wasn't running, it was somehow blocking sites. Uninstalling it using the peer guardian uninstaller that comes with the program immediately fixed everything. I hope that's the same problem the others in this thread were having!

So so glad I stumbled across this forum, I have been driven nuts trying to find a solution as to why my MacBook suddenly decided it would refuse to access 1 site - just 1 - on the entire Internet: www.twitter.com.

Tried DNS, PRAM, clearing browser caches, router configurations, you name it - nada.

And now, I've just un-installed, and re-installed PeerGuardian and - hey presto - it's all working fine once again.

Two words: THANK YOU
