   Resolution

   The DHCP Client Service in Windows XP, depends on these three components:

   AFD
   NetBios over Tcpip
   TCP/IP Protocol Driver

   If one of the above drivers fail to start, then the DHCP Client Service may not start.

   Step I – Make sure that the three driver files are present

   Open Windows Explorer and navigate to %Windir%\System32\Drivers folder. Make sure that the following files are present in the folder:

   afd.sys
   tcpip.sys
   netbt.sys

   If one or more of the above driver files are missing, extract them from the Windows XP CD-ROM or from the ServicePackFiles\i386 folder, whichever is the latest version.

   Step II – Verify the number of Dependencies

   From other sources in the Web, I’ve found that installation of Norton Antivirus (NAV) adds an entry to the DHCP Service dependencies, and removing NAV does not remove the corresponding entry from the DHCP Dependencies.

   To view the dependency services registered for DHCP Client Service, type the following command in Start, Run dialog:

   CMD /K SC QC DHCP

   Verify the output. It should be exactly as below:

   [SC] GetServiceConfig SUCCESS

   SERVICE_NAME: dhcp
   TYPE : 20 WIN32_SHARE_PROCESS
   START_TYPE : 2 AUTO_START
   ERROR_CONTROL : 1 NORMAL
   BINARY_PATH_NAME : C:\WINDOWS\system32\svchost.exe -k netsvcs
   LOAD_ORDER_GROUP : TDI
   TAG : 0
   DISPLAY_NAME : DHCP Client
   DEPENDENCIES : Tcpip
   : Afd
   : NetBT
   SERVICE_START_NAME : LocalSystem

   If additional entries are listed under DEPENDENCIES…

   If any other additional drivers or Services are mentioned in the DEPENDENCIES section, you need to remove them via the registry. Follow these steps:

   Click Start, Run and type Regedit.exe
   Navigate to the following branch:
   Backup the branch to a REG file

   HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Dhcp

   Double-click DependOnService value and set its data as follows:

   Tcpip
   Afd
   NetBT

   Close Regedit.exe

   Step III – Verify that the Dependency Service / components are running

   Next step is to verify that the three dependency components are running. Follow the steps below:

   Click Start, Run and type DEVMGMT.MSC
   In the View menu, click Show hidden devices
   Double-click Non-Plug and Play drivers section
   Double-click the entry AFD, and click the Driver tab
   Set the Startup type to System.
   Start the service. Note down the error message if any.
   Similarly start the two other drivers namely:

   TCP/IP Protocol Driver
   NetBios over Tcpip

   Close Device Manager and restart Windows.
