In this article there you are going to learn about how to fix the different issues concerning computer connectivity over a network for instance at the office or at school or even at home, hang on in there and learn one or two things.
Make sure any computer you want to use is in the same working group. The Workgroup name on any machine should be exactly the same. Always, make sure to use the same case for names (all tops or all bottoms).
Press Start in Windows 7 or higher, type in Workgroup and then select Change Workgroup Name. To change the workgroup name press the Change tab.
Windows 7 introduced a new feature called the HomeGroup that sets things up automatically to allow you to share files between Windows 7, Windows 8, and Windows 10 computers.
3. File and Printer Sharing
Make sure the network adapter is switched on for file and printer sharing. You can allow this by going to Control Panel, Network Connections, right-clicking on a network link, selecting Properties, and testing for Microsoft Networks File and Printer Sharing.
You need to go to the Network and Sharing Center in Windows 7 and higher, then press Advanced Sharing Settings and turn it on there.
4. Correct Subnet and IP addresses
If all of your computers are connected to the same router, you really shouldn't have this problem, but it is worth mentioning.
Ensure sure all machines have the same Subnet mask and Default Gateway. If these aren't the same, then there would be problems linking the machines over the network.
These details can be viewed by going to Start, Run, Type CMD and then typing IPCONFIG / ALL at the command prompt on each computer.
5 Check Firewalls
My recommendation here is to disable the Windows Firewall on all machines first and then try to access the shared folders afterward. Additionally, make sure all third-party firewall programs like Norton or Comodo are disabled.
If you notice that the sharing works with the firewall off, make sure to add File and Printer Sharing to the Windows Firewall and third-party firewall exceptions list
6. Shared permissions
If you get permission you do not have to use this network resource ... Access is denied message, the issue could also be that the shared directory permissions are not correctly set.
You'll need to configure the sharing properly depending on whether you're running XP Home or XP Pro. You can only share files with XP Home through Simple File Sharing. It is pretty quick because they have a wizard to guide you through the process of sharing.
You need to disable Simple File Sharing and set NTFS permissions for XP Pro, and share permissions to allow access for all. Check my post about setting file/folder permissions, or how to share files between computers for more information.
7. Use TCP/IP Protocol
You probably don't have to worry about this either, but just to cover all the bases, you need to make sure the computers on the network all use the Internet TCP / IP protocol to communicate and not IPX / SPX or NetBEUI.
You can go to Begin, Control Panel, Network Connections, right-click on the link to the network, select Properties, and see the protocol is specified in the list box.
8. Username and Passwords
If you have done all of the above correctly and still can't communicate, then you should always try to make sure the usernames and passwords are exactly the same on all devices.
It is best to use passwords on all accounts, and build a new account with the same username and password on each device. Often creating a new account is necessary, instead of just changing the name or password on an existing account. Make sure Administrators are the accounts.
9. Computer Names
Make sure the names of NetBIOS are specific for all computers. NetBIOS names are only 8 characters, so if you named one of the user1 and User2 computers they will have the same name as NetBIOS.
Make sure that a computer name's first eight characters are identical, or you'll be having problems. Remember this is only a concern with very old Windows versions.
10. Local Security Policy
A local security policy is another explanation you might not be able to reach another device across the network.
You can go to the Administrative Tools, Local Security Policy, Local Policies, Security Options, Control Panel. check the following protocol now:
Network access: Do not allow anonymous enumeration of SAM accounts and shares
Make sure that the value is set to Disabled. Also, make sure to disable only the setting that says “SAM accounts and shares” not the one that says “SAM accounts” only.
11. Uninstall anti-virus and Internet Security
Finally, make sure that all your anti-virus programs are either turned off or uninstalled to test out the connection. If you have any Internet Security programs such as Norton Internet Security or Kaspersky Internet Security, disable them!
