Lesson 4- Real World Sharing


In Lesson 4 we go to each of our computers, verify our networking and file sharing settings are correct and make changes when necessary.  We then share several folders and printers on each computer.   We’ll connect to the shares in Lesson 5.

Hello and welcome to Section 5, Lesson 4. In this lesson we’re going to cover real-world sharing. What this means is we’re going to go to each of the computers that we’ve connected to the router. We’re going to check the firewall, make sure it’s off. Check the computer name and workgroup. We’ll check the list of protocols in Windows networking and finally we will share files and printers on each computer.

Then in Lesson 5 we’re going to go back to each computer and browse the network making sure we can see all the computers and all of the shared files and printers we set up. We’ll connect to the shared folders and make sure we have access to them and we’ll install the two shared printers so we can print across the network.

It’s important to remember that when we share our files and printers we are only sharing them with other computers that are connected to our router. No one on the Internet can see our shared files and printers because they are hidden behind the router’s hardware firewall. The security key that we entered into the router and on each of our computers keeps the neighbors from getting on the network, so it’s all very secure.
Sharing on the Family room Computer

We’re going to begin on the family room computer. This is the computer with the USB wireless network adapter. First we need to make sure that the Windows firewall is off. We’ll go to Start, search for firewall, click Windows firewall and it is off. We also have Norton Internet security installed on this computer. We need to make sure it’s firewall is off as well. It says the firewall is secure so we need to go to the settings, web browsing, personal firewall and turn off and will turn off permanently.

Next we need to check the computer name and workgroup we’ll click Start, right-click Computer, go to properties. We’ll go to ‘advanced system settings’, ‘computer name’ and the computer name is ‘Family’ and the workgroup is set to ‘Workgroup’ and that’s correct. If you wanted to change the name worth the workgroup was incorrect we’d click ‘change’ and here you can make changes. We’ll close down System Settings.

Next we need make sure that the network settings are correct. To do that we’ll right-click on the icon for Windows networking, down by the clock. Go to Network and Sharing Center, click ‘Manage network connections’ we’ll find our wireless network connection, right-click on it, go to Properties and we have our list of clients services and protocols. Since Norton Internet Security is installed as a semantic network client and the rest is default for Windows Vista. We need to make sure that the Internet protocol version 4, Properties, is set to obtain an IP address automatically and obtain DNS server address automatically. It is so that’s good.

On your computers you need to pay attention to the icons look like this. This is the icon for protocols. In Windows Vista if you have protocols other than the Internet protocols version 6 and 4 and the two link layer topologies. You need make sure that those extra protocols aren’t set to use file and printer sharing. If they are it can cause problems with sharing between your computers. If on your computers, in Windows Vista, you see more than the 4 default protocols that ship with Windows Vista, what you need to do is click cancel out of this and in Windows Vista in order to get to the Advanced Settings to check for the bindings you need to press alt on your keyboard which will give you the File, Edit, View, Tool and Advanced. We need make sure the wireless network connection is highlighted, go to Advanced and click Advanced Settings. What you are looking for is the bindings. If you see something here other than the Internet protocol version 4 and 6 under File and Print Sharing for Microsoft Networks you need to uncheck it. If you skip this step, there can be problems with sharing files and printers between your computers. Everything looks okay here so we’ll just cancel and close down the network connections.

We’re back in Vista’s network and sharing Center. We’ll start checking the settings from the top and I see a problem here. Our network is set the Public and that will keep us from sharing files and printers with other computers.  We need to click Customize set it to Private, Next and Close. Under Sharing and Discovery we have Network Discovery on, File Sharing on, we have Public Folder sharing off, Printer sharing off, because no printers are on this computer. This setting won’t keep us from connecting to another computer with a printer and printing across the network which will do in Lesson 5. Password protected sharing is off and media sharing is off. Okay all this is good so we’ll move on to sharing some folders.

On this computer we’re going to share the Desktop. To do that we’ll go to Start, click our username, which shows us all the folders that by default Vista has set up for us.  One of them is the Desktop, right-click on it, go to Share and it’s already showing us as the owner. We need to click this down arrow, find Everyone in the list, click Add and we’re going to give everyone on the network full access to the Desktop. By default it’s set to Read which again is just read access. Anyone on the network right now can see the files on this Desktop, but they can’t change or add to files on the Desktop. We’re going to click Reader and change it to Co-owner to give full read and write access to any computer over the network to this desktop. We’ll click Share. The Sharing items says this may take a few minutes. Depending on how many files and folders you have in the folder that you’re sharing this can take anywhere from 30 seconds to several minutes. Just be patient and it will get done. It says our folder is shared. We’ll click done.

We’re also going to share our Pictures folder will right-click on it. Again, we’ll click the down arrow, click Everyone and Add. Then change the permission for Everyone to Co-owner which will give full access. We’ll click Share, it says your folder is shared. We’ll click done and that’s it.

Sharing on the Living room Computer

Now are going to switch to the living room computer. We’re now on the living room computer, it’s running Windows XP and this is the computer that we installed PCI card wireless network adapter. First we’ll make sure the Windows firewall is turned off. We need right-click on the wireless networking icon down by the clock and go to Change Windows Firewall Settings. It is off, so we’ll cancel out of that.

We also need to make sure the firewall in Norton Internet Security is turned off. Inbound firewall is at risk and Advanced firewall is at risk, meaning it’s off. We’ll close our of that.

Next we’ll check the computer name and the workgroup name and a Windows XP there’s a few ways to do that. Before we showed you how to go to Start, right-click on Computer, go to Properties and then Computer Name. To get to the computer name and workgroup. You can also, in Windows XP, right-click on the icon for Windows networking, down by the clock, go to Open Network Connections, since we need to go here anyway. At the top you should see Advanced. If you click that you can go to Network Identification and you get to the same page. On your computer the Advanced might be hidden. On some computers there is a little down arrow looking icon that you click and you’ll find the Advanced.

Here on the computer name tab the computer name is living room and that’s fine, but the workgroup name is MSHOME and this is the default if your computer is running Windows XP home edition. If your computer is running Windows XP Pro or Vista it’ll default to Workgroup. Here we need to click to change and change the workgroup to Workgroup. We’ll click okay. We get confirmation it’s been changed and it tells us we have to restart the computer to make the changes take effect. Click okay and we’re going to say no will restart later.

Next we’ll take a look at the list of networking protocols. We need to right-click on the wireless network connection and go to properties. Here in the list this computer is also running Norton Internet Security. We see a Semantic driver and on this computer it looks like we added the link layer topology the add-on for Windows XP that allows the computer is running on to show up in Windows Vista’s network map. That’s fine to leave. We also see an AEGIS protocol which could be a problem. If this protocol is bound to File and Print Sharing it can interfere with the sharing between computers.

Before we go and check the bindings we need to make sure the Internet protocol TCP/IP, its properties are set to obtain automatically on both. That’s good.  We’ll cancel our of this and to get to the Advanced Properties of the network connection in Windows XP it’s very similar to what you see in Windows Vista. You need to make sure that the network connection is highlighted click Advanced and go to Advanced Settings. The bindings are pretty much exactly what you see in Windows Vista. Here we see that the only protocol that’s bound to File and Print Sharing is Internet protocol so the protocol we found back in the list of client services and protocols the AEGIS protocol is not a problem and we can leave it. We’ll cancel out of that.

Let’s go take a look at the printer that’s on this computer. Go to Start and Printers and Faxes. If Printers and Faxes doesn’t show up in your Windows XP, you need to go to Control Panel and you find it under Printers and Other Hardware. ‘View installed printers or fax printers’ and here’s our printer. We’ve already shared this in Lesson 3. We’ll go ahead and check the settings. Right click on it. Go to Sharing and it is shared under the name HP. That’s good, we’ll just cancel out of that.

On this computer were also going to share the My Documents folder. To get to My Documents, you can click Start and My Documents should show up in the list. Now to share it, if you have the blue common files and folder tasks running on your computer there is a task here for ‘Share this folder’ which brings up the Sharing tab. You can click to ‘Share this folder on the network’. The share name will default to the name of the folder and we can choose whether or not we want to give full access to computers across the network. On this one were not going to. We’ll click okay. If you’ve disabled the blue common files and folder tasks on your computer you can also find sharing if you right-click anywhere in the white space of a folder.  You can go Properties there’s a sharing tab and you get the same sharing options.

Sharing on the Home office Computer

Next we’re going to go to our home office computer. We’re now on the office computer. It’s running Windows Vista and we’ve already checked to make sure that the firewall is off. The computer name is Michael. The workgroup is set to workgroup. We’ve checked the protocol list and Vista’s Network and File Sharing Center and everything is as it should be.

This computer has a printer on it and if we go to Start, Printers. We can see that it’s already shared. This is one of the printers that we shared in Lesson 3. If we right-click on it and go to Sharing you’ll remember that we named it HP to make it easier to share. Just in case you have to type in the name manually. We’ll click okay and close down the printers.

We’re also going to share a MP3 folder on this computer. It’s under Computer and the F drive and is called MP3s. If we right-click on it and go Share. Click the down arrow, click Everyone and Add, we can change the permission level from Reader to Co-owner which will give every computer on the network full access to this folder. We’ll click Share and Done and will close that down.

Sharing on the Notebook Computer

Next we’ll go to our notebook computer. We’re now on our notebook computer it’s running Windows XP and this is the computer that we installed the PC card wireless network adapter. We need to make sure that the firewalls are turned off. We’ll right-click on the Windows networking icon, down by the clock go to change Windows firewall settings. It is off so we’ll cancel out of that.

We’ve also installed a free firewall program on this computer called Komodo and we need to turn it off as well. We’ll right-click on it go to Firewall and Security and change it to disabled.

We’ve already checked the computer name and workgroup on this computer. The computer name is Acer and the workgroup is set to workgroup.

Let’s go check the Windows networking. Again we’ll right-click on the Windows networking icon down by the clock. Go to Open Network Connections. Right-click on the wireless network connection and go to Properties. Here in the list we see a NetBEUI protocal which could be causing a problem. We need to check the bindings on it. We’ll cancel out of this. Make sure the Wireless Network Connection is highlighted. We’ll go to Advanced and Advanced Settings. Down in the bindings section for File and Print Sharing we can see that the NetBEUI protocol is here and it’s checked.  We need to uncheck that. Any protocol other than Internet protocol in Windows XP or in Windows Vista, the Internet protocol 4 or 6, if it’s bound to File and Print Sharing can cause problems with the sharing between computers. So that’s uncheck. That’s good. It’s not bound anymore and we can click okay. We’ll close down network connections.

On this computer were going to share this Movies folder. We’ll right-click on it and go to Sharing and Security.  Click to share this folder on the network. It defaults to the name of folder which is fine. We’re going to allow full sharing to every computer on the network. We’ll click okay and it shared.

So now we’ve gone through all of our computers, we’ve made sure that all the settings are correct and we shared some folders and printers on the computers.

Next what we’re going to do is we’re going to restart all the computers to give them a fresh start and were going to wait about 15 minutes to give them a chance to connect to each other. Before we move on to Lesson 5 where we’ll connect to the shared files and folders and printers.
