I bought a Sentient H264 DVR System from Maplins a couple of years ago now. I have been using the system and works great. I am trying now to view the system on my PC over a network. But keep getting a message login failed whether i try WAN or Internet options. Here are my settings-: Type - Static Web Port - 0080 Media Port - 9000 IP Address - 192.168.000.300 Subnet Mask - 255.255.255.000 Gateway - 192.168.000.001 DNS - 192.168.000.001 Mobile Port - 100 I have enabled the default system password. I have a sky D-Link Router could this be something to do with Port Forwarding? Although why cannot from my home network? I have lost the CD that came with the system, do you guys know if there is any software on there which I need to install for the system to work. Any help guys, would be appreciated. I'm really confused.

How do i check i have a valid connection to the router and dvr. Do i type cmd/ ping-ip address of dvr? What exactly am i looking for?
