I tried something yesterday that didn't work very well and I'm hoping you can spot the error. <br />
<br />
A client of ours wanted to lock down the internet for their users while keeping the managers free to do whatever. <br />
<br />
There are 2 DNS servers there. One forwards out to the internet and I configured the second as a forwarder to opendns.com. DNS2 was configured as a secondary zone to DNS1. I put the 4 XP computer accounts into their own OU and applied a group policy to assign DNS2 as their DNS server.<br />
<br />
When the policy replicated, however, they didn't have access to their main database (hosted on DNS1) or the Internet. <br />
<br />
I ended up having to undo the whole solution last night and now we're back where we started - with DNS2 disabled and all machines pointing to DNS1.<br />
<br />
What do you guys think?

Lockdown internet using DNS server

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
