Windows Vista cannot obtain an IP address from certain routers or from certain non- DHCP

if you go to


http://support.microsoft.com/kb/928233/en-us

it tells you how to get round this problem by regedit to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

and adding a key

my question is how do I work out what the  GUID  is of the network card

my mac of the usb wireless stick is

ZyXEL G-202 Wireless USB Adapter

these are the guid's
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{0f694452-6a70-11db-8eb3-806e6f6e6963}HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{2c40b21f-b5c2-11db-a647-000c76bf5189}

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{AD10F175-FCEB-4446-9011-2E8D200A5FE4}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{B1A58B1D-607D-4AD2-8976-79B2BC3EC94F}

nothing seems to correspond in the driver details
btw mine connects fine but I want to know for future reference I had to tie
down someone's wireless card to the router to get is to connect

This KB article mentions also another registry value,

This KB article mentions also another registry value,  DhcpConnForceBroadcastFlag,
that is global. If you set it, does it help?

If the router or the non-Microsoft DHCP server does not support the DHCP
BROADCAST flag, you can set the following registry entry as follows:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

Value name: DhcpConnForceBroadcastFlag
Value type: REG_DWORD
Value data: 0

it still applies to a specific GUID

Yes. You're right.

If when connected you browse through the GUIDs in the registry (the list you suppplied), you can see which has a content that matches your adapter - You can find the IP for instance..



BTW. Setting DhcpConnForceBroadcastFlag to 0 worked for me.

Change all of them it does not matter you are having the problem with all adapters as I am.  This is a Vista problem that has no solution yet that I can find.  Static IP is the only way for now.
