Re: [BC] Can't access a single site, can't change dns server HTTP error 500 is a problem on their end, not yours. I just checked it and it works fine for me.
If you really want to change your DNS (which isn't bad in itself) press Windows key + R, type ncpa.cpl
Right click your LAN adapter, edit the IPv4 properties.
As a suggestion I use Google DNS: 126.96.36.199 and 188.8.131.52.
