Can't access one site

[w3stfa11]

My brother has a problem accessing one site (craigslist). He can access any other site but not that one. Multiple browsers doesn't help. He can't even ping the site.

I did some google searching and it seems like it's a DNS issue. Should I tell him to restart his router? Or for him to call his ISP? Thanks.

have him try to go to http://208.82.236.208 (craigslist's web server IP). If he can connect by IP, then you are right - it is probably a DNS issue. If he cannot connect by IP, then he has a Firewall or other device filtering/blocking the traffic.

Thanks. Yes, he was able to connect by IP. Does that mean he needs to restart his router or reset it?

Possibly.

I would start by going to the command prompt on the PC and running this command:
nslookup craigslist.com

see what IP it resolves to...is it the same as the one that I posted?

He can also try running:
ipconfig /flushdns

This will flush any entries in the PC's DNS cache and make the PC do an nslookup for a new address.

If his Router is handling DNS for his network, then the router might have a bad address in its DNS cache (if it stores entries in cache). Restarting the router would fix that.

If none of that works, he might have an entry in his HOSTS file that blocks the website. open C:\windows\system32\drivers\etc\hosts with notepad and see what is in there.
