When you try to access shared resources on a Windows 10 PC from a Windows 7 or a Windows XP PC, you receive an error message “The Specified Network Name is No Longer Available”. 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. The issue commonly faced on Windows 7 or XP client computers.
In our environment we have two Server 2008 R2 servers- a bot server and a file server. Basically, as our bot server performs its business-related tasks, it creates and updates .csv files which are located on shares on the file server.
Occasionally, the bot server is not able to access its file server files. When this happens, its error log outputs the Windows error “The specified network name is no longer available” when referencing the target file.
Why does “The specified network name is no longer available” Error occurs?
- Using a device that supports SMB 1.0 on the latest version of Windows 10.
