Optical Duplicator Network Center Troubleshooting

Symptom Problem Solution
The Duplicator Network Center Software won’t detect the Network Duplicator. The Duplicator’s Network Module is pre-configured as DHCP by default. Connect under a DHCP LAN environment and then manually configure the network settings by clicking on the “System” menu and then select Server Setting.
Duplicator Network Device always has a red icon and I can’t connect to it. The red icon is an indication that the network device is currently being used by another user. You can obtain more details about the current connection by right clicking on “Duplicator Network Device” and selecting Details. You can send the other user a request to disconnect by selecting “Request Disconnect”.
The Duplicator Network Device has a yellow “!” exclamation mark on the red icon and I can’t connect to it. This is an indication that the Ethernet port is being over prioritized by the USB port. Make sure that the USB port is not connected while the Ethernet cable is connected.
I’ve connected to the Duplicator Network Device successfully but my PC does not have any drive letter that is associated with the hard drive. The hard drive’s drive letter has not been automatically assigned. Click on the “System” menu and then select Mount Drive. A window appears that allows you to manually assign the drive letter.
I’ve connected to the Duplicator Network Device successfully but my computer asks me to format the hard drive when I click on it. Kanguru Media Manager isn’t installed. The Kanguru Duplicator’s hard drive is formatted with a proprietary file system that requires Kanguru Media Manager to be installed. Install Kanguru Media Manager and reboot your computer.
