# How to use Windows permissions to restrict access to the MDaemon user directory

## This guide will show you how to edit Permissions on the \\MDaemon\\Users folder. This would prevent unauthorized users from viewing potentially sensitive emails that reside on the server.

This article assumes that the actual administrator account is not the account the MDaemon administrator will be using.

This article was designed for MDaemon to run as the SYSTEM account. 

Follow these steps to install and run MDaemon as a SYSTEM service.

1. Start **MDaemon**
2. Select **Setup**
3. Select **Preferences**
4. Select **Windows Service**
5. Verify **Logon Name**, **Password**, and **Domain** are blank. 
     - This indicates MDaemon is not running under a particular account.
6. Click the **Install Service** 
     - If the button states **Remove Service**, the MDaemon service has already been installed.
7. Click **OK**
8. Click **OK** again (MDaemon will then be restarted if changes are made)

Verify the MDaemon service is active and not running under a specified account.

1. Select the Windows **Start** button.
2. Select **Run** or use Windows Search.
3. Enter **services.msc**
4. Find the **MDaemon** service.
5. Verify the **Status** of the MDaemon service is **Running**.
6. Right click the **MDaemon** service.
7. Select **Properties**
8. Select the **Log On** tab.
9. Verify the **Local System account** is selected.
10. Click **OK**

Follow these steps to modify Windows permissions to restrict access to the MDaemon user directory.

1. Open **Windows Explorer**
2. Navigate to the **MDaemon** directory
3. Right click on the **Users** folder
4. Select **Properties**
5. Select the **Security** tab
6. Listed here should be 4 Groups/Users 
     - Administrators
     - CREATOR OWNER
     - SYSTEM
     - Users
7. Select **Edit**
8. Select **Users**
9. Click the **Deny** in the **Full-Control** check-box
10. Select **Add...**
11. Enter the account that will be interacting with MDaemon.
12. Click **OK**
13. Select the account that was just added.
14. Click **Deny** in the **Full Control** checkbox.
15. Click **OK**
