Our company made some changes to the DHCP server, which has affected our departmental Vista clients

It has to do with the Broadcast flag in the DHCP request...

The fix for it is in knowledge base article kb 928233 which is to add a new registry entry in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
with a new DWORD DhcpConnEnableBcastFlagToggle set to a value of 1

Anyway, that fix works fine for existing Vista installs,
but is there a way to add that setting in a WinPE boot.wim? So, I think that somehow I need to run regedit on hive inside boot.wim?

We're deploying some computers from WinPE from USB or CD...but they do not receive IP address from DHCP (I'm assuming that it's because WinPE is based on Vista)

Thanks for any insight!

You can mount the boot.wim file in read/write mode, mount the offline registry in the mounted image and make the changes then unmount the offline registry and unmount and commit the changes to the wim file.
