Windows 用户在尝试访问共享资源时有时可能会遇到意外错误。尝试访问共享文件夹时，他们收到以下错误：指定的网络名称不再可用(The specified network name is no longer available)。
想象一个假设情况，办公室中的计算机网络连接在同一个本地Windows域下。连接到打印机的系统之一用于打印文档并且工作正常，直到有一天用户开始报告他们无法访问用于发送文档以进行打印的共享文件夹。虽然共享文件夹对连接到打印机的 PC 可见，但它会向使用连接系统的用户提供上述错误。
指定的网络名称不再可用
逐一尝试以下解决方案，并检查它们是否有助于解决您的问题：
- 禁用Symantec Endpoint Protection
- (Turn OFF User Account Control)暂时关闭用户帐户控制
- 禁用您的防病毒软件
- 授予共享文件夹的权限
- 在有问题的系统上启用SMBv1、SMBv2和SMBv3
让我们详细研究这些步骤。
1]禁用赛门铁克端点保护(Disable Symantec Endpoint Protection)
此问题的一个已知案例是干扰Symantec Endpoint Protection。因此，如果您在系统上安装了它，请禁用它并查看。
- 右键单击(Right-click)开始按钮(Start)并选择命令提示符（管理员）(Command Prompt (Administrator))并键入命令：smc -stop。
- 按 Enter(Press Enter)，它可能会部分停止Symantec Endpoint Protection。检查它是否解决了问题。
- 如果没有，请尝试以下命令：smc -disable –ntp然后smc -disable -ntp -p <password>。第二个命令禁用防火墙。
- 稍后，要启用Symantec Endpoint Protection ，键入smc -start并启用防火墙，请键入smc -disable –ntp。
2]暂时关闭用户帐户控制(Turn OFF User Account Control)
要隔离问题，请关闭用户帐户控制。Microsoft不建议这样做，因此一旦确定问题，我们将不得不返回。
3]禁用您的防病毒软件
暂时禁用您的防病毒软件，然后检查用户是否可以访问共享文件夹。隔离此案例后启用软件。有时，您的安全软件可能会导致此问题。这就是为什么建议暂时禁用它并检查问题是否得到解决的原因。
4]授予(Grant)共享文件夹的权限
- 右键单击(Right-click)文件夹并在选项中选择属性(Properties)。
- 在“安全(Security)”选项卡中，选择“高级(Advanced)”，然后在“高级(Advanced)”菜单中，转到所有者列表。
- 根据需要验证(Verify)和修改权限。
理想情况下，这应该是文件夹访问问题的第一步，但是，由于错误消息，这可能更多是防火墙或端点保护的问题。
5]在有问题的系统上启用 SMBv1(Enable SMBv1)、SMBv2和SMBv3
如果问题特定于一个或几个系统，我们可能会考虑在有问题的系统上启用 SMBv1、SMBv2 和 SMBv3。供您参考，您可以使用Windows 功能(Windows Features)面板执行此操作，而不必下载第三方软件。

Fix The specified network name is no longer available error on Windows
Windows users at times may face an unexpected error while trying to access shared resources. When trying to access a shared folder, thеy 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.
The specified network name is no longer available
Try the following solutions one by one and check if they help resolve your issue:
- Disable Symantec Endpoint Protection
- Turn OFF User Account Control temporarily
- Disable your antivirus software
- Grant permissions to the shared folder
- Enable SMBv1, SMBv2, & SMBv3 on the problematic system
Let’s delve into these steps in deatil.
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.
- Right-click on the Start button and select Command Prompt (Administrator) and type the command: smc -stop.
- 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.
- 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. At times, your security software might cause this issue. That is why it is recommended to disable it temporarily and check if the problem gets resolved or not.
4] Grant permissions to the shared folder
- Right-click on the folder and select Properties among the options.
- In the Security tab, select Advanced and in the Advanced menu, go to the list of owners.
- Verify and modify the permissions as desired.
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. For your information, you can do that using the Windows Features panel, and you do not have to download third-party software.
