How to Fix It When the Specified Network Name Is No Longer Available

Try These Proven Troubleshooting Tips

An incorrectly specified name is no longer available can occur in a number of ways under the following circumstances:

  • Try accessing a shared network location on your Windows 10 PC from an older Windows computer.
  • Attempt to access the network share using the Server Message Board (SMB) file sharing protocol.
  • Access any network device that supports the SMB protocol.

This error usually occurs when you try to access the share from the client. Access attempts often take a long time before errors occur.

This error usually occurs when a client tries to access a network share or the device does not support the SMB protocol. It can also happen when antivirus software or firewalls block or interrupt access to network shares.

The reason for the specified network name is no longer available error

Server Message Block (SMB) is a file transfer protocol that has been used on Windows systems for many years. Its main purpose is to allow client computers to access remote files on another computer system. The computer saving the file must have the SMB protocol enabled, and the client opening the file must support the SMB protocol.

However, it may fail if the system hosting the file uses a newer version of SMB that the client does not support. Antivirus software, firewalls, and other network issues can also interfere with the SMB file transfer process.

How can I fix the incorrectly specified network name that is no longer available?

This issue applies to Windows 10, Windows 8, Windows 7, and Windows Vista, including 32-bit and 64-bit versions of these operating systems.

Disable your antivirus software. This is the easiest solution to try first and often fixes this error. Most major antivirus programs, such as Norton, Avast, and McAfee, offer the option to temporarily disable protection.

Disable Windows Firewall and Windows Defender. Windows’ built-in security tools can also block the SMB protocol and cause an incorrectly specified network name to no longer be available. Disable these tools to test if this resolves the error.

Make sure you have file sharing enabled on the system you are using. Depending on the operating system you are using, the settings for such file shares may be slightly different. Make sure you have file sharing set up correctly on a Mac or on a Linux system. There are also specific steps to properly set up file sharing on your Windows system.

The SMB protocol requires additional configuration to work on server and client computers. In Windows, you must open Administrative Tools to access Windows features and ensure: Support SMB 1.0/CIFS file sharing activated. Make sure to restart your Windows system for the changes to take effect.

One solution to directly map a network share is to map the server hosting the file by IP address rather than network name. Doing so removes the need to resolve network names and allows your file shares to function properly.

This should be a last resort, as IP addresses on most networks (such as home networks) are usually not static IP addresses. Routers often assign dynamic and constantly changing IP addresses to devices. Therefore, even if using the IP address of the server or computer works initially, it may not continue to work.

Since SMB is a somewhat outdated file sharing technology, consider using P2P or FTP protocols to share files over the network. You can also consider using a cloud storage solution to share files between computer systems.

Is SMB enabled by default in Windows 11?

Windows 11 supports SMB access to shared folders on other systems. However, to share folders and files in Windows 11, you must enable file and printer sharing in the Network and Sharing Center. This setting is enabled by default, but you may have disabled it or Windows Firewall may be blocking it.

If you decide to enable file and printer sharing in Windows 11, you will need to enable password protection so that anyone connecting to your shared folder has not been authenticated.

How to Fix It When the Specified Network Name Is No Longer Available

Try these proven troubleshooting tips

The Specified Name Is No Longer Available error may appear in one of several different ways when:

Trying to access a network shared location on a Windows 10 PC from an older Windows computer.
Attempting to access any network share using SMB (Server Message Blog) file-sharing protocol.
Accessing any network device that supports SMB protocol.

The error usually occurs when attempting to access the share from a client. The access attempt usually takes a long time before the error shows up.

This error usually occurs when the client attempting to access the network share or device doesn’t support SMB protocol. It can also happen when accessing the network share is blocked or interrupted by antivirus software or a firewall.
Cause of Specified Network Name Is No Longer Available Error

Server Message Block (SMB) is a file transfer protocol used on Windows systems for many years. Its primary use is to allow client computers to access remote files on another computer system. The computer storing the file needs to have SMB protocol enabled, and the client accessing the file needs to support SMB protocol.

However, if the system hosting the file uses a newer version of SMB unsupported by the client, it can lead to errors. Antivirus software, firewalls, and other network issues can also interfere with the SMB file transfer process.
How Do I Fix the Specified Network Name Is No Longer Available Error?

This issue applies to Windows 10, Windows 8, Windows 7, and Windows Vista, including both 32-bit and 64-bit versions of these operating systems.

Disable your antivirus software. It’s the easiest fix to try first and often fixes this error. Most major antivirus apps like Norton, Avast, and McAfee provide the ability to disable protection temporarily.

Disable Windows Firewall and Windows Defender. Windows embedded security tools can also block SMB protocol and cause the Specified Network Name Is No Longer Available error. Disable these tools to test if it resolves the error.

Ensure you’ve enabled file sharing on the system you’re using. There might be slight differences in setting up this form of file sharing depending on the OS you’re using. Make sure you’ve correctly set up file sharing on your Mac or file sharing on your Linux system. There are also specific steps to set up file sharing correctly on your Windows system.

SMB protocol requires additional configuration to work on both the server and the client computers. On Windows, you’ll need to open Administrative Tools to access Windows Features and make sure SMB 1.0/CIFS File Sharing Support is enabled. Make sure to restart your Windows system to make sure the changes take effect.

One workaround to map network shares directly is mapping to the server hosting the files via IP address rather than the network name. Doing this will bypass the need to resolve the network name and help get your file share to work properly.

This should be a last resort since IP addresses on most networks, such as a home network, are not usually static IP addresses. Routers typically assign dynamic, changing IP addresses to devices. So even if using the server or computer’s IP address works initially, it may not continue working.

Since SMB is a somewhat outdated file-sharing technology, you may want to consider sharing files over a network by using P2P or FTP protocol instead. You might also consider using cloud storage solutions to share files across computer systems instead.

Is SMB Enabled by Default in Windows 11?

Windows 11 supports SMB in terms of accessing shared folders on other systems. However, if you want to share folders and files in Windows 11, you’ll need to enable file and printer sharing in the Network and Sharing Center. By default, this setting is on, but it’s possible you disabled it or that the Windows Firewall may be blocking it.
If you do decide to enable file and printer sharing in Windows 11, make sure to enable password protection so anyone connecting to your shared folder will still have to authenticate.
