smbprotocol is a Python library designed to interact with servers using the SMB 2/3 Protocol. It provides low-level access to SMB operations, allowing for file and directory manipulation, session management, and authentication against SMB/CIFS shares. The current version is 1.16.1, and the project maintains an active release cadence with multiple updates per year.

This quickstart demonstrates how to establish a connection to an SMB server, authenticate a user, connect to a shared folder, and list its contents. It emphasizes the critical need to explicitly close all resources (Connection, Session, TreeConnect, Open objects) in a `finally` block to prevent resource leaks.
Ensure your SMB server supports SMBv2 or SMBv3. If you are connecting to older systems (e.g., Windows XP, Windows Server 2003 without updates), you will need to upgrade the server or use a different library.
Always wrap your `smbprotocol` operations in `try...finally` blocks to ensure that `.disconnect()` or `.close()` methods are called for all instantiated resource objects. For file-like objects, consider using a `with` statement if available (e.g., `smbprotocol.file.File` does support `with`).
Verify the exact username format required by your SMB server (e.g., `DOMAIN\username`, `username@domain.com`, or just `username` for local accounts). Ensure the password is correct. For Active Directory, you might need to ensure proper DNS resolution and Kerberos setup if using Kerberos authentication.
If integrating into an `asyncio` application, use `loop.run_in_executor()` to run `smbprotocol` calls in a separate thread pool to prevent blocking the main event loop.
Double-check the credentials, ensure the user account is active, and confirm the domain is specified correctly if required for authentication.
Verify the server's IP address/hostname and port (default 445), check local and server firewall rules, and ensure the SMB service is active on the server.
Verify the exact path on the SMB share, ensuring correct spelling and case sensitivity, and confirm the object exists.
Ensure the authenticated user account has the required permissions on the specific SMB share and the target file/directory.
