## Resolution

### Agent is not installed on client machines

Endpoint Central Agent might not have been installed in all computers within the defined scope. Verify whether the Endpoint Central Agents are installed in the client systems that are specified in the Scope of Management. If not, install the agents in the client machine and try again.

Refer to the [online help](https://www.manageengine.com/products/desktop-central/help/configuring_desktop_central/managing_computers_lan.html) for more information related to Agent Installation.

### User Logon Reports settings are not enabled

If User Logon Reports is not enabled, the reports generated will contain null values. Enable the User Logon Reports.

### Multiple Endpoint Central server installations

Maintain only a single Endpoint Central server in your network and remove any additional ones to avoid this error.

To find the presence of additional servers:

- Check the Server IP address from the Endpoint Central Agent Tray icon in the client machine.
- If the tray icon is disabled:
  1. Go to **Start → Run**
  2. Type `regedit`
  3. Navigate to:

```
HKEY_LOCAL_MACHINE\SOFTWARE\AdventNet\DesktopCentral\DCAgent\ServerInfo
```

You can check the `DCServerIPAddress` and `DCServerName` at this location. A different IP address indicates the presence of multiple Endpoint Central servers.

### Obstruction by Firewall running on client machines

Check for any firewall running on the machine where Endpoint Central is installed. It might block the status update messages that come from client machines. Add the Endpoint Central port (default 8020) to the exceptions list.

Steps:

1. Go to **Start** and select **Control Panel**.
2. Select **Windows Firewall**. This opens the Windows Firewall window.
3. Select the **Exceptions** tab and click on **Add Port**.
4. Add the port name and port number.
5. Add:
   - Port **8020** (or your Endpoint Central Server port for HTTP)
   - Port **8383** (or your Endpoint Central Server port for HTTPS)
6. Click **OK**.

### Intervention by security software

Security software like Symantec or McAfee running on client machines may block agent communication with the Endpoint Central server. Stop the security software and try again.

### First logon after Agent installation

The first logon after Endpoint Central agent installation on client machines will not reflect in the report. Only subsequent logins will be tracked.

### Users do not login to the Domain

User Logon reports are available only when users log in to the Windows domain.

If users log in as a local user (this computer) or log in to a workgroup, they will not be tracked.

### The domain is managed as a workgroup

User Logon reports for workgroup environments are supported only for customers running Endpoint Central build **#91022 or later**.

If the Endpoint Central build is lower than **#91022**, user logon details for workgroup users will not be tracked.
