How to take registry backup of current network properties

I want to take back up of registry of the current network settings like IP,Subnet,DNS and all that stuff, in windows xp开发者_开发技巧. How can i do that? Please help.

For Windows XP clients and higher, the netsh command has access to all your nitty-gritty networking configuration. Rather than fool with Registry stuff (which may be incomplete, since the network config is in many places), you might do better by using the netsh dump > ipsettings.bak command to save a configuration script. If you need to restore the settings due to bad changes, simply run netsh exec ipsettings.bak and you're back in business.

Either use the FreeIPSwitcher or (using your chosen language - not specified) backup HKLM\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces
