Default Behavior
DHCP Client is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the DHCP Client service is running as NT Authority\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If DHCP Client fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the Dhcp service is not running because of the error.
Dependencies
DHCP Client is unable to start, if at least one of the following services is stopped or disabled:
- Ancillary Function Driver for Winsock
- NetIO Legacy TDI Support Driver
- Network Store Interface Service
If DHCP Client is stopped, the WinHTTP Web Proxy Auto-Discovery Service fails to start and initialize.
Restore Default Startup Configuration of DHCP Client
Before you begin doing this, make sure that all the services on which DHCP Client depends are configured by default and function properly. See the list of dependencies above.1. Run the Command Prompt as an administrator.
2. Copy the commands below, paste them into the command window and press ENTER:
sc config Dhcp start= auto
sc start Dhcp
3. Close the command window and restart the computer.
The Dhcp service is using the dhcpcore.dll file that is located in the C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 7 installation media.
