How to make your windows network more secure using www.OpenDNS.org

Well this one is really simple.

On your windows 2003 server go to DNS right click the server go to your forwarders and add the opendns dns servers.
Also go to your root hints tab and remove those. (did you ever check if the default root hints are still valid nah I know, if you use em you should also update them)

Now for all your outgoing lookups the windows server queries the opendns servers.

Why is this safe?

Block the bad sites and whitelist the good.

Phishing Protection

We operate PhishTank.com, the world's most trusted source of phishing data. We integrate that data into an intelligence feed on our DNS servers to keep everyone on your network safe from phony sites trying to steal personal information.

Domain Blocking

You want to secure your network and have control over what resolves. We give you that control by providing the tools to block any website or DNS zone on the Internet, all through an easy-to-use interface.

Adult Site Blocking

Safeguard your kids, protect your students, or limit your corporate liability by blocking adult websites. Our adult site blocking solution can be deployed in minutes and provides granular levels of blocking. Hundreds of school districts are already using OpenDNS to achieve CIPA compliance. Did we mention it's completely free?

Web Proxy Blocking

Prevent people on your network from bypassing the access restrictions you put in place. Blocking Web proxies helps ensure your network remains secure.

Domain Whitelisting

We provide a (growing) list of Web content filtering categories to block, but sometimes there is a domain you want to make sure is never blocked, even if it's listed in a feed. Have the final say with our Domain Whitelisting feature.
