2 computers can be connected to the Internet, but they can t access the Internet or share files

Vista hasn't used it, so I don't know, if it's two XPs, I can tell you why! You go and see if XP's guest account is disabled! It's definitely disabled, it's all open, and it's time to access sharing!

Vista doesn't know if you need to turn on the guest I haven't used it.

With dual network cards, since there is always a machine turned on, it is rarely used, so it is not in detail. Let's take the system as an XP (Internet server) as an example.

Aren't you two computers? One of them serves as an Internet server and installs two network cards. **The cable is connected to the cat, and the cat's network cable is connected to one of the network cards (the parameters do not need to be set, the default). The other NIC is connected to your switch and the parameters are set.

For example: IP

maskgateway is empty.

DNS empty.

The other computer is also connected to the switch, and the NIC parameters are set.

For example: IP

maskgateway

DNS Then, establish an Internet connection on the XP to ensure that you can access the Internet, open the attributes of the online neighbor, and share the Internet connection.

Note that sometimes firewalls block sharing.

Of course, third-party shareware is also available, but it is not recommended to use it because there are few machines.

Vista I almost forgot, so I passed by the top sticker,

1. First of all, operate on the computer that has been connected to the printer, use the shortcut key "Windows+X" to open the following options, and click "Control Panel".

2. Then click "View Devices and Printers".

3. Then right-click on the connected printer and select "Printer Properties".

4. Click "Share".

5. Then check the box in front of "Share this printer".

6. Then click "OK" below

7. Then find that there are two "person" avatars next to the connected printer, which means that the sharing has been set successfully.

8. Then open the control panel on another computer and click "Add Device".

<>10. Then it will prompt that the printer has been successfully added, click "Next".

You can then successfully set up two computers to share a single printer, note: both computers must be in the LAN workgroup. (as shown below).

1. How to set the local IP of the local area network

Many internal computers are in the same LAN (computers connected to the same router or switch become LAN), so we can first set a fixed IP address for each computer, such as one for, the other is, and the subnet mask is generally the same, so as to prevent conflicts caused by automatic assignment of IP addresses.

2. Open the guest account (most systems have it turned on by default).

The "guest" account is enabled on all computers. Start menu——— click on the logged-in user's avatar ——— manage other users——— click on Guest Users – Enable Guest Users.

3. Enable guest account permissions

After ——— settings——— Control Panel——— Management Tools——— Local Security Policy——— Local Policy——— User Rights Assignment, find the option to access this computer from the network, add the guest user, if there is one, it is not needed; Then see if there is a guest in this computer who refuses to access from the network, and if there is no guest, you don't need to set it.

4. Enable LAN tethering settings

——— Network & Sharing Center ——— advanced sharing settings, open Home or Work, select Enable Network Discovery in Network Discovery, Enable File and Printer Sharing in File and Printer Sharing, and Turn Off Password Protected Sharing in Password-Protected Sharing.

5. Set up a shared folder

Then right-click on the folder you want to share——— Properties——— Sharing-Advanced Sharing-Permissions, select "everyone", then add, set the permission level to "Read", and you can share. If you want to cancel, go to "Advanced Sharing" and remove the "Sharing" checkbox.

6. Quickly find a way to share computer files

As long as you can share it within a local area network, and then we want to find the file shared on the other party's computer, just use the win + r combination shortcut key to open the run dialog box, and then enter the local IP address of the other party's computer in the opening, such as the file shared on the computer, we just need to enter after opening, and then click OK to find the shared file on the other party's computer.

Buying a router on one computer Setting up a printer for sharing another computer Add printer is done.

Buy two baskets of teeth to pass the file.

You don't have to go to an Internet café, you have to have a LAN if you want to connect with other computers. Set up the original computer to be able to operate remotely. As long as the original computer is turned on all the time, "MSTSSC" is running on the new computer, running the IP of the original computer, and logging in with the user of the original computer.

You can directly manipulate the system and files of the original computer. However, you're better off creating a shared file on your original computer. This gives you direct access.

First of all, it's impossible to have a network cable!

Then, open "Online Neighbors", select "Set up home or small office network", and after the two next steps are "Choose a connection method", select the middle item here. The next step is to "provide a description and name for this computer", which can be left out here, next step. Go to Name your network and enter the workgroup name.

Next, go to "File & Printer Sharing" and select "What do you want to do?" to enable file sharing and printer sharing. Next, wait for the build, and after a while pop up "It's almost done...

, select the last item to complete the wizard. Next, done.

Once both computers have set up such a network, double-click on "Internet Neighbors", "View Workgroup Computers", find the other computer, and you can create a shared file.

Buy a router to share two computers, and you're good to go.
