Solution for Windows Vista cannot obtain an IP address

[monsitj]

Vista and non-Microsoft DHCP servers :

You want to connect Windows Vista to a network and a router or other device, configured as DHCP (Dynamic Host Configuration Protocol). However, the router or other device does not support the DHCP BROADCAST and Vista refuses to connect to the network.

This problem occurs because Windows Vista and Windows XP Service Pack 2 (SP2) running on a different indicator BROADCAST. Regarding XP SP2, in packages of discovery, DHCP is set to 0 (off) while for Vista, the BROADCAST indicator in DHCP discovery packets is not disabled. It follows that some routers and some non-Microsoft DHCP server can not manage the DHCP discovery packets.

What to do then ... ?

It will be necessary to intervene in the register of Windows Vista. Attention because any error in the procedure could cause a crash of Windows Vista. We therefore strongly recommend to backup your registry before intervening in it. To save your registry you can follow the tuto de Marie-XP on Vista:
How to back up the registry Windows Vista

Once the registry backed up, follow the steps below:

1. Press the "Windows" and simultaneously press the "R" in the fields of the window that appears type "regedit" and click OK.
   
2. Go to the registry subkey and then click the following: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\(GUID)"
3. Arrived at this place several registry subkeys are present, click the subkey (GUID) that matches the network adapter connected to the network.
   
4. In the Edit menu click New and click DWORD 32 bits.
   
5. In the field "New Value # 1" type "DhcpConnEnableBcastFlagToggle" and press "Enter."
   
6. Click the right mouse button on "DhcpConnEnableBcastFlagToggle" and click on "Edit."
   
7. In the "Value data" type "1" then click "OK."
   
8. Close the Registry Editor and restart Windows Vista.

Now, you can now connect Windows Vista to the rest of the network.

Thanks,

I recently had problems with Vista Home Premium. Unfortunately, I am running into issues when trying to connect to my network using a commercial router with DHCP enabled. The router already has multiple PCs connected to it (XP and Vista) w/o any issues. For some reason Vista will not obtain an IP address. But now it has been resolved.
