 Security Agent users need to update
                                components. From the web console, configure component update
                                settings in , or grant users the privilege to update in
                                     > .

 Real-time Scan Service has been disabled or is not functional 
 | 
 If the Real-time Scan Service (Apex One NT RealTime
                                Scan) has been disabled or becomes non-functional, users must start
                                the service manually from Microsoft Management Console. 
 | 
| 
 Real-time Scan was disabled 
 | 
 Enable Real-time Scan from the web console ( > ). 
 | 
| 
 Real-time Scan was disabled and the Security Agent is in Independent mode 
 | 
 Users need to disable Independent mode first. After
                                disabling Independent mode, enable Real-time Scan from the web
                                console.

| 
 The Security Agent is connected to the network
                                but appears offline 
 | 
 Verify the connection from the
                                web console () and then check connection verification logs
                                    (). 
If the Security Agent is still offline after
                                verification: 
- 
                                    
If the connection status on both the server and Security Agent is offline, check the
                                        network connection. 
                                 
- 
                                    
If the connection status on the Security Agent is offline but online
                                        on the server, the server's domain name may have been
                                        changed and the Security Agent connects to the server
                                        using the domain name (if you select domain name during
                                        server installation). Register the Apex One server's domain name to the DNS
                                        or WINS server or add the domain name and IP information
                                        into the "hosts" file in the following folder on the agent
                                        endpoint: <Windows
                                            folder>\system32\drivers\etc 
                                 
- 
                                    
If the connection status on the Security Agent is online but offline
                                        on the server, check the Apex One firewall settings. The firewall
                                        may block server-to-agent communication, but allow
                                        agent-to-server communication. 
                                 
- 
                                    
If the connection status on the Security Agent is online but offline
                                        on the server, the Security Agent's IP address may have
                                        been changed but its status does not reflect on the server
                                        (for example, when the agent is reloaded). Try to
                                        redeploy the Security Agent.

 Smart protection sources are unavailable 
 | 
 Perform these tasks if the
                                agent loses connection with smart protection sources: 
- 
                                    
On the web console, go to the Endpoint Location screen () and check if the following endpoint location settings have been
                                        configured properly: 
                                    
                                 
- 
                                    
On the web console, go to the Smart Protection Source screen
                                            () and then perform the following tasks: 
                                    
                                        - 
                                            
Check if the Smart Protection Server settings on the
                                                standard or custom list of sources are correct. 
                                         
                                        - 
                                            
Test if connection to the servers can be
                                                established. 
                                         
                                        - 
                                            
Click Notify All Agents after
                                                configuring the list of sources. 
                                         
                                     
                                 
- 
                                    
Check if the following configuration files on the Smart
                                        Protection Server and Security Agent are synchronized: 
                                    
                                 
- 
                                    
Open Registry Editor and check if the agent is
                                        connected to the corporate network. 
                                    Key: 
                                    HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\iCRC
                                            Scan\Scan Server 
                                    
                                        - 
                                            
If LocationProfile=1, the Security Agent is connected to
                                                the network and should be able to connect to a Smart
                                                Protection Server. 
                                         
                                        - 
                                            
If
                                                  LocationProfile=2, the Security Agent is not connected
                                                to the network and should connect to the Smart
                                                Protection Network. From Internet Explorer, check if
                                                the Security Agent endpoint can
                                                browse Internet web pages. 
                                         
                                     
                                 
- 
                                    
Check internal and external proxy settings used
                                        to connect to Smart Protection Network and Smart Protection
                                        Servers.  
                                    For more information, see Configuring Internal Agent Proxy Settings and Configuring External Agent Proxy Settings.

For conventional scan agents running Windows 7,
                                        Server 2012, and later versions, verify that the tmusa
                                        driver is running. If this driver stops, agents cannot
                                        connect to smart protection sources for web reputation.
