Your internal (?) DNS server seems to be screwed up or offline, or not forwarding DNS requests to Internet DNS servers. I would check that first.<br />

I have a win2k3 file server with about 30 users using Winxp in one of our sites. &nbsp;Each server works independently on its own network/subnet mask. &nbsp;In addition we have a managed firewall and we have a web filter. &nbsp;About 3 weeks ago my server stopped going out into the WAN. &nbsp;If I try and open IE and go out on the web it times out. &nbsp;If I try and ping any website it times out. &nbsp;I did not have this issue before. &nbsp;I checked my DNS and that has not changed. &nbsp;The funny thing is when I put an alternate DNS of 4.2.2.2 I am able to go the internet through a normal browser and through a command line. &nbsp;In fact my web filter came up and I had to authenticate in order to go out on the web. &nbsp;When I take the alternate DNS off, bingo back to square A and cannot get online. &nbsp;I am however, &nbsp;am able to ping the router and any other servers on the network/subnet and even remotely log onto any other server via remote admin whether I have the alternate DNS or not.<br />
Any suggestions as to why this may be happening?

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.
