YNQ™ Adds Server/Client SMBv3 Capabilities To WinCE
The SMB protocol was introduced to Win CE in version 6 back in 2006. Microsoft kept supporting the protocol including in Win7, but did not maintain the SMB library or introduce upgrades for Windows CE to incorporate later protocols – SMB2 and SMB3.
The outdated versions of Windows CE are still in use today mainly in the industrial world, in sectors and areas such as automation and manufacturing, scales and analytical instruments, controllers, ATMs, gas and fluid system components, and energy automation. Due to the nature of these industries, an upgrade to a new operating system is impractical as it will require huge efforts and resources. These circumstances prevent the outdated Windows CE based machines to connect to network shares on Windows machines running SMB version 2 or later

The table above presents the outcome of SMB negotiations between two machines. The version of SMB used between the two machines will be the highest dialect supported by both.
When supported only by SMBv1, a WinCE machine will enforce the usage of SMBv1, which in newer operating systems is no longer supported by default (see article Bid Goodbye to Malware Prone SMBv).
Integrating the off-the-shelf YNQ library into Win CE enables connectivity with any SMB client or server supported machine. Read more …
