    Can you tell me a little more? Not sure I'm reading your issue correctly. Does the server have one network card? If so, is that attached to the hub?

    More details would help.

    Thanks

    Kevin

How can proxy server bolked ?


A proxy server is a computer used to act as the one contact point between your computer and the open Internet. The primary benefit of a proxy server as that it can cache (store) Internet web pages and other content on its disc drives. When a user connected to the proxy server requests a web page or content that was previously accessed by another user, the proxy server can deliver that content/page from its cache to the new user without having to go out to the Internet.

Network administrators can configure a proxy server to prevent users from reaching dangerous or unauthorized web sites. So if your computer is connecting to the Internet through a proxy server, you will be using whatever restrictions the network administrators have set up. If you are not using only your home network, you are most likely NOT using a proxy server. If you are using a school, university, organization or corporate network, then you are most likely USING a proxy server to connect.

VPN in Microsoft Server 2003


The full form of VPN is Virtual Private Network. VPN gives extremely secure connections between private networks linked through the Internet. It allows remote computers to act as though they were on the same secure, local network. Allows you to be at home and access your company's computers in the same way as if you were sitting at work.

Almost impossible for someone to tap or interfere with data in the VPN tunnel. If you have VPN client software on a laptop, you can connect to your company from anywhere in the world. VPN goes between a computer and a network (client-to-server), or a LAN and a network using two routers (server-to-server). Each end of the connection is a VPN "endpoint", the connection between them is a "VPN tunnel".

When one end is a client, it means that computer is running VPN client software. You can use a virtual private network (VPN) to connect components to one network by using another network. VPN do this by "tunneling" through the Internet or another public network. With a VPN, connections across the public network can transfer data by using the routing infrastructure of the Internet, but to the user, the data seems to travel over a dedicated private link.

A VPN gives you the benefit of a dial-up connection to a dial-up server, plus the flexibility of an Internet connection. Using an Internet connection you can connect to resources all over the world. If you have a high-speed Internet connection at your computer and at your office, you can communicate with your office at full Internet speed. This is much faster than any dial-up connection that uses an analog modem.

VPNs use authenticated links to make sure that only authorized users can connect to your network, and they use encryption to make sure that others cannot intercept and cannot use data over the Internet. A Tunneling Protocol is a technology that helps make the transfer of information over the Internet more secure from one computer to another.

VPN technology also permits a corporation to connect to its branch offices or to other companies over a public network, such as the Internet, while helping to maintain secure communications. The VPN connection across the Internet logically operates as a dedicated wide area network (WAN) link.

VPN in Windows 2003 Server: You need a high speed Internet connection to configure and run VPN server. Two individual lan card must be present in a single system where you want to configure a VPN Server. The lan cards should ping each other. Also need a User which's Dial in allow access should be enable. Microsoft 2003 server two tunnelling protocols for a secure VPN connection, one is PPTP (Point-to-Point Tunnelling Protocol) which Provides data encryption using Microsoft Point-to-Point Encryption. The other is L2TP (Layer Two Tunnelling Protocol) which Provides data encryption, authentication, and integrity using IPSec.

Steps to create VPN Server in 2003 Server: At first I go to Start and point to Administrative Tools, then click Routing and Remote Access. Then I click the server icon that matches the local server name in the left panel of the console. If the Routing and Remote Access service was previously turn on, you may want to reconfigure the server.

To reconfigure the server Right-click the server object, and then click Disable Routing and Remote Access. Click yes to continue when you are prompted with an informational message. Then Right-click the server icon and then click configure and Enable Routing and Remote Access to start the Routing and Remote Access Server Setup Wizard. After that click Remote access (dial-up or VPN) to turn on remote computers to dial in or connect to this network through the Internet. Then I have Click to select VPN. In the VPN Connection window I click the network interface (Lan) which is connected to the Internet and go the IP Address Assignment window, then I click Automatically because there was present a DHCP server in network. However, if DHCP is not available, you must specify a range of static addresses.

If you use from a specified range of addresses, open the Address Range Assignment dialog box and Type the first IP address in the range of addresses that you want to use in the Start IP address box. Type the last IP address in the range in the End IP address box. Windows calculates the number of addresses automatically. After that I have accept the default setting of No, use Routing and Remote Access to authenticate connection request and finally Click Finish to turn on the Routing and Remote Access service and to configure the server as a Remote Access server.
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. It also need for security purpose.<SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Verdana','sans-serif

How to use comupter as sever


Proxy server
Use a Computer as a Proxy Server
Small networks can still take advantage of a proxy server.
The Microsoft Windows operating system allows you to turn your computer into a proxy server.
A proxy server is a central computer on the network connected to the Internet.
Other computers on the network use the machine to connect to the Internet.
The Internet Connection Sharing (ICS) configurations on the machine allow you to turn your computer into a proxy server.

Click the Windows "Start" button and select "Control Panel."
Double-click "Network and Internet Connections."
Double-click "Network Connections" to view a list of network card settings.
Right-click your network card icon and select "Properties."
For most users, this icon is labeled "Local Network."
Click the "Advanced" tab.

Check the box named "Allow other network users to connect through this computer's Internet connection" in the section labeled "Internet Connection Sharing."
A warning message pops up telling you that your IP is reset for the proxy computer.
Click "OK."

Reboot your computer for the settings to take effect.
You also need to reboot each client machine on the network to ensure they see the proxy server.
Turn a Computer Into a Server
When you have more than several computers and users who want to share files and resources, whether in your home or in a small office, you can convert a computer into a server.
Building a server out of a computer will allow users to access files whichever computer they use to access them.
An example of the resources that can be shared is a printer and shared folders such as photos and documents. Here's how to convert a computer into a server.

Prepare your computer.
Clean up the computer with unnecessary files to save on space.
If your computer is really old, install the latest operating software so that it is compatible with the rest of the computers that will share its resources.
For this example, we are installing Windows XP.
Check the hard drive space or capacity if you have enough.
You can do away with 256MB sized old computer, but you may want to think about adding more disk space for future needs.
You can easily buy extra internal or external hard drives to bump up your disk space to a capacity that you would desire.
Try purchasing a 10GB extra disk drive then insert it in computer or connect via a serial port or USB hub it if it is external drive.
To install the hard drive driver on XP, let the hardware wizard run you through the options.
You can install the driver with the installation CD software that your hard drive came with.
Follow the options during installation. ,


Check your computer if the network card (ethernet card) is functioning properly. if it does not, you would need to install a NIC or Network Interface Card.
Some old computers have 10 megabit cards, but if you want to have high network performance and better connectivity through your LAN (Local Area Network) then you would need to upgrade your NIC by installing a 100 megabit or 10 gigabit NIC.
Install your network card driver using the installation CD that came with it then follow the installation wizard.

Get a network router. Connect this router to your high speed connection.
The most common ones to use are Netgear, Linksys or DLink routers.
Choose a wireless router so that if you have wireless users they can connect easily (plus this will save you on trying to connect cables to the router all over the place).
Set up your network connections.
Click on "Start," "Control Panel and "Network and Internet Connections."
Pick a task from the options listed or pick a control panel icon, in this case "Network Connections."
If you are set up to pick up the IP Address of your computer automatically, one you have installed your NIC in Step 4 and rebooted, it will pick up the connections automatically whether plugs in using a LAN or network cable or using wireless card.

Rename your computer. Name it so that it can easily be identifiable in your network.
You can either name it simply "SERVER" to be easily recognized, but it is all up to you how you want to name your server.
To name your server if you are using Windows XP, you can right-click on "My Computer" then click on "Properties."
Go to "Computer Name" tab then click on "Change."
Other Windows operating systems or versions would have this feature located somewhere else. Read the owner's manual that your computer came with it.

Create a shared folder by going to "My Computer" and "C:\Documents and Settings\All Users\Documents."
Create a new folder by right-clicking on the screen, then click on "New Folder."
Name the new folder "Shared Files" or anything that can easily be identifiable.
Take note that on Windows XP, any folder that you create and then dragged into the "Shared Documents" folder will be automatically shared by everyone.
You can restrict certain folders by dragging the folder out of the "Shared Documents" folder, then right-clicking on the file folder, clicking on "Properties," then the "Sharing" tab and finally "Make this Folder Private."
Create a shared resource by adding a printer or fax to use. Go to "Start."
Click on "Printers and Faxes" and "Add a Printer," then let the installation wizard that came with the printer or fax guide you.
Name your printer or fax (for example, "Shared Printer").
Then once the printer is installed, set it up so that you can share it by right-clicking on the "Shared Printer," then on "Properties," "Sharing" tab and finally on "Share this printer."
Connect any computer to your server.
Go to each computer and ensure they are connected on the same router.
Then go to "Start" and "Run," type in "EXPLORER," then on the menu click on "Tools" and "Map Network Drive."
A window will pop open where you will assign a "Drive" letter and a "Folder."
Choose any driver letter, for example "G" to denote "Group" drive or "S" to denote "Shared Drive," then type in the IP address of the server.
To do this, go to the server, then go to "Start" and "Run," type in "CMD" then type in "IPCONFIG." This will display your server's IP address.
Type the IP address on the "Folder" field on the computer.
You can also try if the computer will automatically find it by choosing the drive letter then clicking on the "Browse" button on the "Folder" field.
Start using the shared resources by going to the drive letter that has been assigned on your computer.

Difference between proxy server firewall and something called a gateway firewall ....Just a homework question..need another angle other then the veryconfusing textbook


In computer networks, a proxy server is a server (a computer system or an application program) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.
A proxy server has many potential purposes, including:
  • To keep machines behind it anonymous (mainly for security).[1]
  • To speed up access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.[2]
  • To apply access policy to network services or content, e.g. to block undesired sites.
  • To log / audit usage, i.e. to provide company employee Internet usage reporting.
  • To bypass security/ parental controls.
  • To scan transmitted content before delivery for malware.
  • To scan outbound content, e.g. for data leak protection.
  • To circumvent regional restrictions.
A proxy server that passes requests and replies unmodified is usually called a gateway or sometimes tunneling proxy.
A proxy server can be placed in the user's local computer or at various points between the user and the destination servers on the Internet.
A reverse proxy is a (usually) Internet-facing proxy used as a front-end to control and protect access to a server on a private network, commonly also performing tasks such as load-balancing, authentication, decryption or caching

A firewall is a dedicated appliance, or software running on a computer, which inspects network traffic passing through it, and denies or permits passage based on a set of rules.
It is a software or hardware that is normally placed between a protected network and an unprotected network and acts like a gate to protect assets to ensure that nothing private goes out and nothing malicious comes in.
A firewall's basic task is to regulate some of the flow of traffic between computer networks of different trust levels. Typical examples are the Internet which is a zone with no trust and an internal network which is a zone of higher trust. A zone with an intermediate trust level, situated between the Internet and a trusted internal network, is often referred to as a "perimeter network" or Demilitarized zone (DMZ).
A firewall's function within a network is similar to physical firewalls with fire doors in building construction. In the former case, it is used to prevent network intrusion to the private network. In the latter case, it is intended to contain and delay structural fire from spreading to adjacent structures.
Without proper configuration, a firewall can often become worthless. Standard security practices dictate a "default-deny" firewall ruleset, in which the only network connections which are allowed are the ones that have been explicitly allowed. Unfortunately, such a configuration requires detailed understanding of the network applications and endpoints required for the organization's day-to-day operation. Many businesses lack such understanding, and therefore implement a "default-allow" ruleset, in which all traffic is allowed unless it has been specifically blocked. This configuration makes inadvertent network connections and system compromise much more likely.

Can HP 1410 printer support LAN.


HP 1410 is not a network printer. If you want network printing, you must purchase a printer that features network printing.

You can designate a pc to act as network server and plug printer into that server, and then print from another computer on the same network

Sharing cannon printer MP170


If you want to make your printer a Stand-alone device (no need to be connected to a computer, just directly to the router) you may want to look at getting a Print-Server.

But if you just want to share the printers, you will have to install the printer separately on both computers (since they use 2 diff drivers for the printer), then share it on the vista computer. at this point you should now be able to print on both machines
