How do I map a network drive using Synology Assistant?

Purpose

This article provides steps for mapping a network drive using Synology Assistant on a Windows computer.

For DSM 7.0 and above: Control Panel > File Services > SMB > SMB.
For DSM 6.2 and earlier: Control Panel > File Services > SMB/AFP/NFS > SMB.

In Control Panel > Security > Firewall > Edit Rules, make sure that your firewall rules allow traffic on network ports used by Windows file server (i.e., ports 137, 138, 139, and 445).
Make sure that your user account has Read/Write or Read only permissions for the shared folder that you want to map as a network drive. Refer to this article for more details.
There are additional DSM settings that may block SMB access. Refer to the On your Synology NAS section in this article to avoid such configurations.

Go to the Download Center > select your Synology NAS model > Desktop Utilities to download and install Synology Assistant.
Launch Synology Assistant on your computer.
Find and select your Synology NAS. Click Map Drive.
Enter your username and password and click Next.
Select the shared folder you want to connect to and click Next.
Select a letter you want to use for your network drive. Tick the Reconnect at logon checkbox if you want the network drive to automatically reconnect each time you log in to Windows. Click Next.
Check the summary of your network drive. Click Finish to complete the setup.
You can now access the mapped drive from Windows File Explorer on your computer.

Notes:

If you have implemented one of Windows Hello sign-in options (facial recognition, fingerprint, or PIN) and received errors while setting up the connection, refer to this article.
Refer to this article for instructions on how to map network drives using Windows File Explorer.
If you are still unable to complete the setup successfully, and you are also unable to map network drives using Windows File Explorer, refer to the For Windows PC section of this article for further troubleshooting.
Windows XP only supports SMB1. If Synology Assistant is installed on a Windows XP computer or any computer that only allows SMB1 connections, make sure that the Minimum SMB protocol is set to SMB1 on your Synology NAS. Refer to this article for more details.
