我在 Windows 7 中也遇到了类似的问题。我发现，如果您尝试修改的接口上的链接已关闭，您会收到消息“DHCP 已在此接口上启用”。如果插入电缆（建立链接），相同的命令可以正常工作。
I had a similar problem with Windows 7. I found that if the link is down on the interface you are trying to modify, you get the message "DHCP is already enabled on this interface." If you plug a cable in (establish a link), the same command works fine.
我花了好一会儿才“？”在命令中解决这个问题，因为我遇到了同样的问题，但这是在 Windows 7 中对我有用的语法：netsh interface ip set address name="Local Area Connection" 来源=dhcp
It took me a while of "?" in the command to figure this one out as I had the same issue, but here is the syntax that worked for me in Windows 7: netsh interface ip set address name="Local Area connection" source=dhcp
