For the past few months, I've noticed I can no longer access samsclub.com and techsmith.com through IE, Netscape or Firefox. Earlier, I tried Pinging samsclub.com and it's IP address. No luck.
I just unplugged my router and took the cable modem directly into one of my PC's (all running XP Pro) and am able to access both sites.
I've got Norton Systemworks and Spybot S-D on all machines. I can't find any logs of these sites being blocked.
Checking earlier posts, I did a search for hosts files. The only thing I found was a sample hosts file in the Win32 folder. It didn't contain any sites to block.
Any ideas why this might be happening?
