8. Troubleshooting 
1. 
How do I setup a SNTP (Simple Network Time Protocol) server? 
Answer: In the Windows XP operating system, click Start   select Control Panel   
choose Add/Remove Programs    click the Add/Remove Windows 
Components button 
 click Networking Services  select the Simple 
TCP/IP Services check box  and then click ‘OK’ to finish the installation of 
Simple TCP/IP Services. After that, enter in the host’s IP address on the 
Time Server page.  
2. 
How do I verify the network connection between my workstation and the 
SNMP-NV6 card? 
Answer: Check the network connection by typing the following command ping 
HostName or IP address at your workstation. 
3. 
In the Web Browser, I can see the Login page but cannot login. 
Answer: Please check the IP address of the SNMP-NV6 card and the PC you trying to 
login from. If both of the IP addresses are not in the same LAN, run the 
EzSetting program to configure the User Limitation to Allow Any.  
 
4. 
How do I refresh the NetBIOS table in Windows operating system? 
Answer: Sometimes the IP address of the SNMP-NV6 card will be changed, but the 
host name will remain the same. Although Windows
 
will update its NetBIOS 
table periodically, you can force it to purge its cache immediately by typing the 
command nbtstat –R in the shell. After that, you can connect to the SNMP-
NV6 card by its host name. 
5. 
How can I get the IP address and MAC address of my computer? 
Answer: For Windows system: type ipconfig /all at the DOS prompt. For UNIX system: 
enter ifconfig in the shell. 
6. 
I am unable to ping or connect to the SNMP-NV6 card? 
Answer: Check the following items: 
1)  Check all the network connections.  
2)  Ensure that your PC and the SNMP-NV6 card are in the same network 
segment. If you don't have a router, they must be in the same network 
segment.   
3)  You can connect to the SNMP-NV6 card only if your PC and the SNMP-NV6 
cards are using the IP addresses from the same IP address block. Normally, 
private LANs use the IP addresses from one of the following blocks.  
10.0.0.0  ~  10.255.255.255 
172.16.0.0  ~  172.31.255.255 
192.168.0.0  ~  192.168.255.255 
 
The SNMP-NV6 card's default IP address (192.168.1.100) is from the last 
block. If your LAN is using a different address block, you will not be able to 
connect to the SNMP-NV6 card via the LAN. 
  Under such situation, you can choose to:
