Based on the additional info (which I will add to the discussion page) it sounds like you have a problem with DNS (Domain Name Server) which resolves friendly names like wiki.answers.com into IP addresses. It seems likely your client computers have cached the DNS entry for Google but can't resolve any other names to IP addresses. I believe this because the client computers can perform new google searches which rules out the possibility that you can just see cached internet content.
Assuming your server is running DNS, which I believe is the default for MS Server 2003, the chances are that making the private address of your server (the IP address of the Server LAN interface) the primary DNS entry for the clients and removing any secondaries will solve your problem.
I would manually configure the TCP/IP settings on one client and see if this solves it. If it does you can go on to change the DHCP settings if you are using DHCP once you know it works.
If your server is not running DNS you will have to either install/enable DNS or edit the firewall on the server to allow it to proxy DNS requests (Port 53 on TCP and ideally UDP) which I believe can be done using SOCKS proxy.
Don't be suprised if your users can't even access google when you go back to work, if I am right about the cause the google DNS cache entry will expire at some point and then your users won't even have access to that.....
An error 138 network error - access denied error on Google Chrome indicates that the computer is unable to access the internet. The first thing to check is that either the Ethernet cable is plugged into the computer or the Wi-Fi connection is turned on and able to access the internet. If this has been checked and is working it could be a Windows or third party firewall issue, which can be fixed by allowing access to Google Chrome in the firewalls 'allowed programs' area. Once access has been given the computer may need to be restarted to allow full access.
Network Interface Card Its a card that you attach to your computer to interface( or access) network resources and the internet
A personal network filter used to restrict access to particular Internet resources from a local computer.
Computer with internet access. Network cables connected to each machine. Program installed on each computer.
Remote access to a computer is the ability to log onto a another computer using the one you are on. This is done by internet, or by by being on the same network.
Here is a link to check availability from another computer if you can access the Internet, but not the Google website. If this page can connect, Google is probably up.
NIC stands for Network Interface Card. It is connected to the motherboard of the computer. It provides the device with a MAC address and allows a device to access a computer network such as the internet.
A Network Interface Card (NIC) is needed to connect a computer to a network. It allows a computer to communicate with other devices on the network by sending and receiving data packets. Without a NIC, a computer cannot access network resources or connect to the internet.
The computer would not leave the local network and therefore not have internet access.
Windows Firewall
Direct access is designed to give the user of a computer direct access to their internal network over the internet, and is in many ways similar to VPN's.
the action of gaining access to a computer or a network by entering a username and password
