The DNS Client service now has Started next to its name but I get the same error message when I try to start the DHCP Client service.
Oh! And I just realized that I missed your instruction on downloading RepairDNS...I just tried to and my computer (not the infected one) won't let me download it, saying it's a dangerous file or something like that.
Can you make a picture of DHCP service permissions in registry? Sorry, but it is really difficult for me and I believe for you to work like this. These are some non-standard and rarely seen procedures. I haven't had something like this in years.
