I recently cleaned my computer of the virus Windows Defense Center, but afterwards my dhcp was not working. I can still connect to the internet with my static IP. DHCP is not working because of a dependency issue, but I checked and the only dependencies are tcpip, afd, and netbt. However, when I right click on my computer and go to manage, AFD doesn't even show up on the services. But if I try to manually start it from the command prompt, it claims it is already running. I'm at a real loss as to what to do, but I'd really like to avoid reinstalling Windows XP.

Also, just for further clarification, I checked under the device manager and it also says AFD is running.

When you attempt to start the Service manually, the following error may be displayed:Error: Could not start the DHCP Client Service on local computerError 1068: The dependency service or group failed to start.ResolutionThe DHCP Client Service in Windows XP, depends on these three components:* AFD* NetBios over Tcpip* TCP/IP Protocol DriverIf 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 presentOpen Windows Explorer and navigate to /Windir/System32Drivers folder. Make sure that the following files are present in the folder:* afd.sys* tcpip.sys* netbt.sysIf one or more of the above driver files are missing, extract them from the Windows XP CD-ROM or from the ServicePackFilesi386 folder, whichever is the latest version.Step II - Verify the number of DependenciesFrom other sources in the Web, I've found that some versions of Norton Antivirus (NAV) adds an entry to the DHCP Service Dependencies, and removing NAV does not remove the appropriate value from the DHCP Dependencies.To quickly determine the Dependency services for DHCP Client Service, type the following command in Start, Run dialog:CMD /K SC QC DHCPVerify the output. It should be exactly as below:[SC] GetServiceConfig SUCCESSSERVICE_NAME: dhcpTYPE : 20 WIN32_SHARE_PROCESSSTART_TYPE : 2 AUTO_STARTERROR_CONTROL : 1 NORMALBINARY_PATH_NAME : C:WINDOWSsystem32svchost.exe -k netsvcsLOAD_ORDER_GROUP : TDITAG : 0DISPLAY_NAME : DHCP ClientDEPENDENCIES : Tcpip: Afd: NetBTSERVICE_START_NAME : LocalSystemIf 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 fileHKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Dhcp* Double-click DependOnService MULTI_SZ value and set it's data as follows:TcpipAfdNetBT* Close Regedit.exeStep III - Verify that the Dependency Service / components are runningNext step is to verify that the three dependency components are running. As the three components are actually the Kernel Drivers (Driver Service), you need to manage then via the Device Manager. Follow these steps:* 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 Networking Support Environment, 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.nass -- http://www.nasstec.co.uk
