Establishing local data exchange between computers connected to the same wireless network is a basic task for many users. There's often a need to quickly transfer large files to a laptop or share a media library on a smart TV without the need for external hard drives or flash drives. Windows 10 This process is standardized, but has a number of nuances related to security policies and network discovery settings.
Before getting started with the technical part, you should make sure that all devices involved in data exchange are on the same subnet. This means they must be connected to the same Wi-Fi router, even if one is using a wired connection and the other is wireless. If the computers see each other in the list of network devices, but the folders remain inaccessible, the problem lies in the access rights or firewall settings.
In this article, we'll detail the process for turning a regular directory into a network resource. You'll learn how to properly configure a network profile, activate the necessary services, and avoid common errors such as when the system requires a password or simply doesn't recognize a shared folder. Proper configuration will allow you to create a fully-fledged home media server or a convenient work tool.
Checking the network profile type and discovery
The first and most critical step is determining the network type assigned by your operating system when connecting to Wi-Fi. Windows 10 treats new connections as public by default, automatically hiding your computer from other devices and blocking incoming connections. To enable file sharing, you need to change this status to "Private Network."
To do this, open the system settings and go to "Network & Internet." Select your active Wi-Fi connection and find the profile switch. Set it to "Private." Only then will the system allow other devices on the local network to see your PC and request access to resources.
Next, you need to enable network discovery. Without it, your computer will be invisible to your router's neighbors. Go to Control Panel, select Network and Sharing Center, and click Change advanced sharing settings. Here, you need to enable the following options for the current profile:
- 📡 Turn on network discovery (allows your computer to see other devices and be visible).
- 📂 Enable file and printer sharing (opens ports for data transfer).
- 🔐 Allow Windows to manage HomeGroup connections (optional, but useful for automation).
⚠️ Attention: If you're in a public place (a cafe or airport), never enable the "Private Network" profile or share your data. This will make your personal files vulnerable to attacks from hackers on the same Wi-Fi network.
Configuring folder sharing settings
Once the network settings are in order, you can begin sharing a specific directory. Windows 10 allows for flexible permissions: you can grant full control over files or restrict guests to read-only access. This is especially important if multiple users have access to the folder.
Right-click the folder you want to share and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box. In this window, you can also configure the limit on concurrent users and add comments that will be visible to other network members.
To manage permissions for specific users, click the "Permissions" button. By default, the "Everyone" group is selected, which has read-only permissions. If you want other users to be able to edit, delete, or create files in this folder, select the group and check the "Full Control" box in the "Allow" column.
It's also important to check the "Security" tab in the folder properties. Sometimes permissions are granted in the access settings, but access is denied at the NTFS file system level. Make sure "Everyone" or the specific user you want to grant access to is listed in the user groups, and that they have "Read & Execute" and "Write" permissions.
Managing passwords and accounts
One of the most common connection issues is the requirement to enter a username and password. By default, Windows 10 requires the remote user to have a valid account on the server computer with an identical password. This protects data, but creates inconvenience on a home network.
If you're in a trusted home environment and want easier access, you can disable the password requirement. To do this, return to "Advanced Sharing Settings" (the same place you set up discovery). At the very bottom of the page, find the "All Networks" section and select "Turn off password-protected sharing."
However, if you decide to leave password protection enabled (which is better from a security standpoint), you'll need to create an account on your primary computer. Go to "Settings" → "Accounts" → "Family & other users" and add a new user. Make sure to remember the username and password, as you'll need to enter them when connecting from another device.
| Action | Enabling a password | Disabling the password | Recommendation |
|---|---|---|---|
| Security | High | Low | Turn on in offices |
| Convenience | Low (input needed) | High (automatic) | You can turn it off at home |
| Difficulty of setup | Average (requires accounting) | Low | Depends on experience |
| Risk of leakage | Minimum | Average (with poor Wi-Fi) | Use guest Wi-Fi |
What to do if the password is not accepted?
If you entered the correct password but the system returns an error, try entering the server computer name followed by a backslash in the login field, followed by the username. Format: COMPUTER_NAME\User_Name. This helps the system understand which account database to use for authorization.
Opening ports and configuring a firewall
Sometimes all the settings are correct, but the connection fails due to blocking by the built-in Windows Defender. The firewall may consider attempts to connect to network folders as suspicious activity, especially if the network profile is incorrectly defined or third-party antivirus software is installed.
To check, open Control Panel → Windows Defender Firewall. Select "Allow an app or feature through firewall." Find "File and Printer Sharing" in the list and make sure the checkboxes for private and, if necessary, public networks are checked.
The key here is the operation of the SMB (Server Message Block) service. This protocol is responsible for file transfers. In Windows 10, only SMB 3.0 is enabled by default, but older devices (for example, some TV models) Samsung or LG) may require SMB 1.0 support.
To check or enable support for older protocols (if required for compatibility):
- Open Control Panel and select Programs and Features.
- On the left, click "Turn Windows features on or off."
- Find "SMB 1.0/CIFS File Sharing Support" in the list.
- Expand the branch and check the box next to "SMB 1.0/CIFS Client" and/or "SMB 1.0/CIFS Server".
- Click OK and restart your computer.
⚠️ Attention: Protocol SMB 1.0 This option is considered outdated and vulnerable to ransomware (such as WannaCry). Enable it only if you know for sure that your older device doesn't support SMB 2.0 or 3.0, and be sure to update the firmware of that device if possible.
Connecting to a shared folder from other devices
Once you've completed the setup on your Windows 10 computer, you can proceed to connecting. The easiest way to find the shared folder is to use Network Places. Open File Explorer and select Network in the left pane. If network discovery is enabled correctly, you'll see your computer's name.
If the computer doesn't appear in the list, you can connect directly using its IP address. Find out the local IP address of the server computer (command ipconfig The command line will show an address like 192.168.1.55. In the address bar of File Explorer on the client device, enter: \\192.168.1.55 (replace the numbers with your IP).
Connecting smartphones, TVs, or media boxes typically uses the DLNA protocol or built-in file managers with SMB support. In the app, select "Add device" or "LAN/SMB," and it should automatically find your computer. When prompted for credentials, enter the username and password of the Windows user with access rights.

Common errors and how to fix them
Despite the apparent simplicity, users often encounter error codes such as 0x80070035 ("Network path not found") or 0x80070043 ("Network name not found"). Most often, the problem stems from the services responsible for discovery being stopped.
Check the status of the following services (click Win + R, enter services.msc):
- 🔍 "Function Discovery Resource Publication" - must be running and set to automatic mode.
- 📡 "Function Discovery Provider Host" - similar, requires autostart.
- 💻 "Computer" (Computer Browser) - relevant for mixed networks with Windows 7/XP.
It is also worth paying attention to third-party antivirus software (Kaspersky
