Privacy policy. This step-by-step article describes how to install virtual private networking VPN and how to create a new VPN connection in servers that are running Windows Server For a Microsoft Windows XP version of this article, see With a virtual private network, you can connect network components through another network, such as the Internet. You can make your Windows Server based computer a remote-access server so that other users can connect to it by using VPN, and then they can log on to the network and access shared resources.
VPNs do this by "tunneling" through the Internet or through another public network in a manner that provides the same security and features as a private network. Data is sent across the public network by using its routing infrastructure, but to the user, it appears as if the data is sent over a dedicated private link.
A virtual private network is a means of connecting to a private network such as your office network by way of a public network such as the Internet. A VPN combines the virtues of a dial-up connection to a dial-up server with the ease and flexibility of an Internet connection.
By using an Internet connection, you can travel worldwide and still, in most places, connect to your office with a local call to the nearest Internet-access phone number. If you have a high-speed Internet connection such as cable or DSL at your computer and at your office, you can communicate with your office at full Internet speed, which is much faster than any dial-up connection that uses an analog modem.
This technology allows an enterprise to connect to its branch offices or to other companies over a public network while maintaining secure communications.
Virtual private networks use authenticated links to make sure that only authorized users can connect to your network. The tunneling is completed through one of the tunneling protocols included with servers running Windows Server , both of which are installed with Routing and Remote Access.
The Routing and Remote Access service is installed automatically during the installation of Windows Server By default, however, the Routing and Remote Access service is turned off. Click the server icon that matches the local server name in the left pane of the console. If the icon has a red circle in the lower-left corner, the Routing and Remote Access service hasn't been turned on.
If the icon has a green arrow pointing up in the lower-left corner, the Routing and Remote Access service has been turned on. If the Routing and Remote Access service was previously turn on, you may want to reconfigure the server. To reconfigure the server:. Click to select VPN or Dial-up depending on the role that you intend to assign to this server.
In the IP Address Assignment window, click Automatically if a DHCP server will be used to assign addresses to remote clients, or click From a specified range of addresses if remote clients must only be given an address from a pre-defined pool.
In most cases, the DHCP option is simpler to administer. However, if DHCP isn't available, you must specify a range of static addresses. Click Next to continue. If you clicked From a specified range of addresses , the Address Range Assignment dialog box opens. Click New. Type the first IP address in the range of addresses that you want to use in the Start IP address box. Windows calculates the number of addresses automatically.
Accept the default setting of No, use Routing and Remote Access to authenticate connection requests , and then click Next to continue. For the remote access server to forward traffic properly inside your network, you must configure it as a router with either static routes or routing protocols, so that all of the locations in the intranet are reachable from the remote access server.
The number of dial-up modem connections is dependent on the number of modems that are installed on the server. For example, if you have only one modem installed on the server, you can have only one modem connection at a time.
The number of dial-up VPN connections is dependent on the number of simultaneous users whom you want to permit. By default, when you run the procedure described in this article, you permit connections. To change the number of simultaneous connections, follow these steps:. You can also configure a static IP address pool.
Configure the dial-in properties on user accounts and remote access policies to manage access for dial-up networking and VPN connections. Machines came with stickers on them that showed a Product Key for the Windows licensed for the system. With these systems if you reload XP you should load XP from a manufacturers "OEM" installer CD in which case activation is already taken care of before any service packs are installed.
In the panel on the right, if the XP copy is not a preactivated one, you will see Activation Status. If it IS a preactivated one you won't see Activation Status. While these can be installed on name brand hardware Dell, HP, etc. Originally they could but Microsoft deactivated all of those XP keys to prevent piracy, since it was discovered later that those keys would activate anything on any hardware. Even with all current updates applied from Windows Updates, Windows XP still has many, many open vulnerabilities in it.
If you have to run it, you may be interested in spending an evening reviewing the information on the Unofficial Windows XP Service Pack 4 located here:. Look for Community Update Packs. Even today as of this writing Microsoft has closed most if not all known vulnerabilities in Windows XP but the problem is that the fixes are scattered through many multiple hotfixes many of which were released for specific Large Corporation demands where they still have to run XP for specific applications as well as the Point Of Sale and embedded releases of XP.
The Unofficial Service Pack 4 is an attempt to consolidate those together. While it's not endorsed by Microsoft it is still a useful tool for those instances where hardware requires the use of XP for example, older Modbus cards, etc.
Trust me, nobody including Microsoft is going to come up with a reasonable justification for replacing a 5 million dollar industrial plant controlled by an XP system just to upgrade the controller PC with Windows Office Office Exchange Server.
