Please refer to the How to share data locally using the Synology server as a File Server for further background information about this article. This article will cover tips and common error messages for Windows-based systems with regards to mapping network drives.

Seamless integration between Windows and the Synology System

To allow for easy integration between Windows and the Synology system, it's recommended to use the same username and password on both the Windows computer and the Synology system. This way, users can access the Synology system without being prompted for a username or a password. This section will cover how to identify the username on a Windows System. To set the username on the Synology system please look here.

Clarification Note in the following image that Synology Demo User is not a user name. This is a screen name (or the name of the user), which is used for a "friendlier" interface for users to select their profile. This is not what Windows uses as the username.
Method 1 To identify the username, from the Administration-ranked profile, Go to Control Panel Administrative Tools Computer Management On the left hand pane, go to Computer Management System Tools Local Users and Groups Users Under the Full Name category is where the screen name of the account can be found (Synology Demo User); under the Name column is the username of the account.
Method 2 Go to Start/Windows Orb Type cmd in the Run/Search box Type set in the Command Prompt The username is the third property from the bottom

Start-up scripts

A start-up script is a batch file to automate the creation of map drives when a user beings a Windows Session. This method of mapping drives can be used instead of using the Windows Explorer or the Synology Assistant. This method of mapping drives is meant for experienced Windows Administrators in a multi-computing business environment.

Creating a Start-up Script Create a plain text file, titled login.bat with the following code net use * /d /y net use z: \\synologybox\synodemo /user:synodemo password /persistent:yes And place the file in the user's start-up directory, or assign it to start-up when the user logins to the Domain Controller
Notes With regards to the file name login.bat, any file name can be used, however the extension must be .bat

Error 53

Before anything else, verify your network connection properties and make sure "Client for Microsoft Networks" item is installed and enabled. Otherwise, connecting to shares will fail with error 53 without much details.

A common error seen with Windows computers is Error53, or more ambiguously, user permission errors due to Windows caching permissions. This is seen when the Guest account is enabled on the Synology System, and a user attempts to access a private share on the Synology system. The user may not be able to see the prompt for asking credentials, or see a network path resolution error. The following steps are designed to purge Windows of any cached permission it remembers and set up the Synology system to verify the credentials of a user before giving access to a private share.

Step 1 Go to Start/Windows Orb Type cmd in the Run/Search box Type net use * /d /y in the command prompt and and press enter.
Step 2 Go to the Disk Station Manager of the Synology System Proceed to Privileges -> Users Double Click the Guest account and disable it.
Step 3 Verify that no network drives appear from Windows Explorer
Step 4 Launch Control Panel on the Windows Computer Open the User Accounts Manager
Step 5 Select the account currently in use, or wished to clear the permissions of Click Manage my network passwords
Step 6 Clear the entire list Note Here is where Windows can be program to remember a credential when it is asked to use a specific network resource
Step 7 Close all programs and restart the computer. Proceed by mapping a drive for Windows Windows should display a prompt for username and credentials if the permissions are purged correctly.
Notes For a faster method of performing step 4, 5, execute the following Go to Start/Windows Orb Type control userpasswords2 in the Run/Search box Click Advanced Click Manage Passwords Purge (or add to) the list
