How to detect SMB and NTLM version of remote share

Introduction

When investigating an issue with backup to network share, you may need to check what what SMB protocol version and NTLM versions a network share supports.

This is useful in cases where there is an unexplained connection failure to a share (unsupported SMB protocol version) and in case an error "Access denied" appears when credentials are correct (possibly NTLM version mismatch).

Description

Prerequisites:

Acronis Cyber Protect Cloud, Acronis Cyber Backup: Operation fails with “Windows error: (0x80070180) You can't connect to the file share because it's not secure"

Symptoms

You installed a Windows update (version 1709 and later),
Backup, replication or another operation with a destination network share fails with:

Windows error: (0x80070180) You can't connect to the file share because it's not secure. This share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack. Your system requires SMB2 or higher. For more info on resolving this issue, see: https://go.microsoft.com/fwlink/?linkid=852747
