Question
I have assigned a static ip, subnet to the computer, but the ipconfig shows IP address is 0.0.0.0 and subnet mask 0.0.0.0.. Why?
Answer
An existing IP address on the network has the same IP address. You may use tracert ip, WINS and DNS records to find out another computer using the same IP.
If your laptop users frequently disconnect from one network segment and reconnect to another network segment, they may not be able to access the second network. Resolution will be run ipconfig /registerdns.
