DHCPCSVC]
- Move code from dhcp to dhcpcsvc - Export ServiceMain from dhcpcsvc - Now our DHCP service is compatible with the Windows architecture [DHCP] - Remove dhcp from build [IPHLPAPI] - Use dhcpcsvc APIs to control the DHCP service - Add a missing DhcpCApiInitialize - Fix include path in the rbuild file [BOOTDATA] - Add DHCP to the service list to be loaded by svchost in the netsvcs group - Add the correct registry keys in the DHCP service key for loading by svchost - Remove dhcp.exe from bootcd - Part 3 of 3 svn path=/trunk/; revision=47288
