Mark works as a Network Administrator for ABC.com. The company has a Windows 2003 single
domain-based Active Directory network. The network has five Windows 2003 member servers and
200 Windows XP Professional client computers. One of the member servers named VPNS is
configured as a VPN server. The VPNS internal interface is on a 192.168.0.1/24 private network.
The VPN server’s IP address is 192.168.0.25 with a subnet mask 255.255.255.0.

Mark installs a new Windows 2003 server named FSERVER with default settings. FSERVER is
configured as a file server. The file server’s IP address is 192.168.0.28 with a subnet mask
255.255.255.0. The VPN users on the network complain that they are unable to access files stored
