Suppose your network adapter(lan and wlan) is assigning a private address automatically. and the address range is169.254.x.x.how would you reset?

in command prompt.

netsh winsock reset

command is not working some time.

it happend when there is no DHCP available or when a duplicate IP address exists ,, and this169 series is the autopmatic ip series sets by windows ...reseting network service will do the job if the DHCP and or ur static ip configured is Idle.

If it is DHCP, then in command prompt --> ipconfig /release

then --> ipconfig /renew

By GUI..we can get new ip by diagnosing adapter..

you can make abatch file with the following data:

ipconfig /release

pause

ipconfig /renew

pause

and that will be reset the networkcard to obtain new IP from DHCP Server.

When a Microsof Windows wokstation is unable to contact a functional DHCP server, an APIPA (Automatic Private IP Addressing) IP, in the169.254.0.1 to169.254.255.254 IP address range, is assigned to that computer. All APIPA devices are assigned the default network mask255.255.0.0 on the same subnet.

In order to obtain an IP address from the local DHCP server, you need to ensure that a functional DHCP server resides on the same network as the workstation / computer and that said computer is able to access the DHCP server accordigly. If all is in place, you can open an elevated command shell and enter the following commands:

ipconfig /release

ipconfig /renew.

Alternatively, you can also assign a static IP address to that computer, however this is not recommended in an domain environment where DHCP servers are available.
