DHCP service can not start causing the network connection to display a yellow exclamation problem. Solution

Today, a customer took a computer, Win7 system, said that the onboard NIC can not access the Internet after connecting to the Internet cable, reinstall the driver according to experience. Check the TCP/IP protocol, proxy settings, and more. Did not find any problems. Just the customer said to buy a wireless network card. After the installation of the new wireless network card, the yellow exclamation mark still glared at me.

There was a rescue with the 360 ​​first-aid kit, but it still didn't solve the problem. Holding the attitude of a dead horse as a living horse doctor, manually set up IP and DNS. I didn't expect the exclamation mark to disappear. Because it is the IP that I set manually, it is definitely related to DHCP, so I went to Service.msc and checked it. Sure enough, DHCP did not start. Startup Startup~~~~~ is not started, report 1608 error. . . . . Continue to check the reasons. . . Searching online, it seems to be because of the dependency problem. Said that Internet Connection Sharing (ICS) is not open. However, the ICS service cannot be opened. There are also problems with account permissions, system files being corrupted, etc. The fixes have been tried, and the IP is still not automatically obtained.

The last thing to go around, find a solution in an article abroad. 1. Go to the registry: HKEY_LOCAL_MACHINE\\System\\ControlSet001\\Services\\DHCP2. Find DependOnService on the right side, which should have three values ​​NSI Tdx Afd. 3. Delete Tdx4. Restart the computer

The DHCP service that should be resolved cannot be started.
