DHCP client service with option 12

Hi,

I have a problem with DHCP Client Service component in an XPe image. I
need to request the target hostname to a DHCP Server, but I don't know
how to configure the option 12 on the DHCP request.

I have seen on this component some registry entries in the following
path:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DHCP\Parameters
\Options\

Below this path, there are some values for each option, but I don't
know the right data configuration of KeyType (REG_DWORD) and
RegLocation(REG_MULTI_SZ) for option 12.

Does anybody know these configurations?.

In addition, I don't know if once I have received the hostname, I
could set it without a machine reboot. Does anybody know how can I set
a new hostname on XPe without a reboot?

Thanks in advance.

Ruben
