This is not the case with a Windows Server 2003 guest though. The Internet not working issue is caused by when the guest operating system queries for DNS Server from Shared Network (NAT) virtual router, the guest OS is configured to use the same DNS servers which are used by the physical host computer. So, the problem with Windows Server 2003, Server 2008 and Vista as guest OS cannot access Internet is by design.

Most computers, including Virtual PC 2007 virtual machines can easily access Internet using Shared Networking, as easy as right after operating system is installed, which enable DHCP by default. Beside, Shared Network (NAT) allows user to easily plug and play or move the virtual machine or physical machine to different network configurations such as different Wi-Fi wireless access point, home or office network. NAT is also useful to allow virtually unlimited number of IP addresses to connect to Internet, thus administrator is not limited by the amount of IANA assigned-IP address allocated space. Shared Networking or NAT allows computers or hosts on a private network to access the Internet using a single IP address, without exposing the PCs (or virtual machines) to the external network, significantly reduce security risk. In the case of Virtual PC, it uses a virtual NAT router which built on host computer’s default active network connection to allow guest operating system to access Internet via the host’s Internet connection. NAT ( Network Address Translation) is an easy shared networking technique that masquerading or transceiving network traffic through a router that involves re-writing the source and/or destination IP addresses and the TCP/UDP port numbers of IP packets as they pass through. For example, ping, trace route, ftp, sftp, telnet and SSH using IP address instead of domain name or host name, user can successfully connecting to the remote server. However, when IP address is used, access to the external server on Internet may work. After installing Windows Server 2003, Windows Server 2008 and Windows Vista into Microsoft Virtual PC’s virtual machine (VM) (update to Virtual PC 2007 SP1) as guest operating system, and set the Networking Settings for the VM to use Shared Network (NAT) as the network adapter, the Internet appears to be not working where web browser (Internet Explorer, IE and Firefox) cannot connect, find, locate or browse to website.
