10.0.0.0 is not a valid ip address. Zero cannot be used unless it follows a number...like 10 or 20 etc. It cannot be used alone. 192.168.11.0 would be a broadcast. In other words, all stations with IP addresses 192.168.12.1-255 would recieve the broadcast. If you want to assign an IP address, assuming IP addresses are static, you first need to know the network address and subnet mask. You can check another computer on the network to get this info. For example. Computer1 = IP is 192.168.12.11 and subnet mask is 255.255.255.0. The network address is 192.168.12 and station ID is 11. To assing Computer two with an IP address just add one to the station ID and you get 192.168.12.12. You can use this address as long as it is not already assigned. If it is assigned then you get an IP address conflict. Now, if the network is setup to use DHCP (Server assigned IPs), then you would setup your TCP/IP settings to us DHCP. Sometimes you have to login to the server (as with Border Manager and sometimes you don't even need to login to recieve an IP. Just check the TCP/IP properties from a workstation that is currently working.
