Cannot Access http://www.samknows.com

Whenever I try to access Samknows.com I recieve  an 'Address Not Found' in Firefox. I have occaisionly been able to access the site a few times but very rarely.
I also recieve 'Page Cannot be Displayed' in IE 6 when trying to access.
I have no problem viewing any other site or using applications like MSN, UTorrent, Steam, Thunderbird.
Thanks

I can get to it OK, what address do you get if you do a tracert in a command prompt e.g. of you are on a windows pc type 'tracert www.samknows.com';
mine looks like this:
traceroute to www.samknows.com (80.77.246.44), 64 hops max, 40 byte packets
1  192.168.0.1 (192.168.0.1)  1.138 ms  0.838 ms  2.063 ms
2  lo0-plusnet.thn-ag3.plus.net (195.166.128.80)  33.098 ms  32.527 ms  31.932 ms
3  vl303.thn-gw1.plus.net (84.92.3.177)  45.541 ms  37.003 ms  32.747 ms
4  ge2-21-cr0.thn.uk.as6908.net (195.72.128.21)  32.118 ms  32.596 ms  31.953 ms
5  470.gi3-3.rt0.the.core.lchost.net (195.72.128.50)  54.457 ms  34.322 ms  32.473 ms
6  xifos-gw.customer.lchost.net (213.230.194.102)  32.593 ms  31.990 ms  39.081 ms
7  80-77-246-44.ph0x.co.uk (80.77.246.44)  33.011 ms  32.413 ms  31.952 ms

Can you see what the DNS settings are in your router?

Are these the same as the ones here https://portal.plus.net/my.html?s=0&action=refresh_browser?
If not update them to match otherwise you could try the openDNS ones to see if that makes a difference http://www.opendns.com/

Re: Cannot Access http://www.samknows.com

Result! They were different, changed them and I now have access. I can only imagine that I was using older settings for when I joined up back in 2003.
Many thanks for your assistance.

Re: Cannot Access http://www.samknows.com

Your original settings were also valid!  PN has four DNS server addresses 212.159.6.9  212.159.6.10  212.159.13.49 and 212.159.13.50
It's likely changing the servers has caused your router to flush its DNS cache (which probably held an invalid IP address for Sam Knows) - especially if you needed to reboot it for the settings to take effect.
If the DNS was manually set on the PC and not on the router you could try flushing the PC's DNS cache manually if you run into problems again (Command Prompt > ipconfig/flushdns) - (also works if DNS was set automatically on the PC).  If it's set on the router, a reboot often fixes things.
