xp下，reg query 的 /s 和 /v 开关好像不能一起使用，改一下：

@echo off & setlocal enabledelayedexpansion
set "v1=HKLM\SYSTEM\CurrentControlSet\Control\Network"
set "v2=HKLM\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces"
set "s=EnableDHCP IPAddress SubnetMask DefaultGateway"

for /f "delims=" %%i in ('reg query "%v1%" /s') do (
        set "v=%%i"
        if /i "!v:~,4!" == "HKEY" (
                for %%a in ("!v!\..") do set "ID=%%~nxa"
        ) else for /f "tokens=1,2*" %%a in ("!v!") do (
                if /i "%%a" == "Name" if "%%c" == "本地连接" goto :Next
        )
)

:Next
for /f "tokens=1,2*" %%i in ('reg query "%v2%\%ID%"^|findstr /i "%s%"')do (
        set "v=%%k" & set "%%i=!v:\0=!"
)

if /i "%EnableDHCP%" == "0x1" (
        echo,IP 地 址：%DHCPIPAddress%
        echo,子网掩码：%DHCPSubnetMask%
        echo,默认网关：%DHCPDefaultGateway%
) else (
        echo,IP 地 址：%IPAddress%
        echo,子网掩码：%SubnetMask%
        echo,默认网关：%DefaultGateway%
)
pause
