The specified network name is no longer available

Windows users at times may face an unexpected error while trying to access shared resources. When trying to access a shared folder, they get the following error: The specified network name is no longer available.

Imagine a hypothetical case where a network of computers in an office are connected under the same local Windows domain. One of the systems which connected to the printer is used to print documents and was working fine, till one day users start reporting that they are unable to access the shared folder used to send the documents for printing. While the shared folder is visible to the PC connected to the printer, it gives the mentioned error to users using the connected systems.

Try the following solutions one by one and check if they help resolve your issue:

1] Disable Symantec Endpoint Protection

One known case of this issue is interference with Symantec Endpoint Protection. So if you have it installed on your system, disable it and see.

  1. Right-click on the Start button and select Command Prompt (Administrator) and type the command: smc -stop.
  2. Press Enter and it might partially stop Symantec Endpoint Protection. Check if it solves the issue. If not, try the commands: smc -disable –ntp and then smc -disable -ntp -p <password>. The second command disables the firewall.
  3. Later, to enable the Symantec Endpoint Protection type smc -start and to enable the firewall, type smc -disable –ntp.

2] Turn OFF User Account Control temporarily

To isolate the issue, turn OFF the User Account Control. This is not recommended by Microsoft so we would have to turn to back once we identify the problem.

3] Disable your antivirus software

Temporarily disable your antivirus software and check if the users can access the shared folders after that. Enable the software once this case is isolated.

4] Grant permissions to the shared folder

  1. Right-click on the folder and select Properties among the options.
  2. In the Security tab, select Advanced and in the Advanced menu, go to the list of owners.
  3. Verify and modify the permissions as desired.Change user permissions

Ideally, this should have been the first step for folder access issues, however, owing to the error message, it is probably more of an issue with the firewall or end-point protection.

5] Enable SMBv1, SMBv2, & SMBv3 on the problematic system

If the issue is specific to one or a few systems, we might consider enabling SMBv1, SMBv2, and SMBv3 on the problematic systems.

Hope something here helps you.
