Windows Vista Cannot Obtain An IP address From Certain Routers

CAUSE:- This issue occurs because of a difference in design between Windows Vista and Microsoft Windows XP Service Pack 2 (SP2). Specifically, in Windows XP SP2, the BROADCAST flag in DHCP discovery packets is set to 0 (disabled). In Windows Vista, the BROADCAST flag in DHCP discovery packets is not disabled. Therefore, some routers and some non-Microsoft DHCP servers cannot process the DHCP discovery packets.

RESOLUTION:- Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps: 

1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list. 

2. If you are prompted for an administrator password or for confirmation, type your password, or click Continue. 

. Locate and then click the following registry subkey:

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

In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.

3. On the Edit menu, point to New, and then click DWORD (32-bit) Value.

4. In the New Value #1 box, type DhcpConnDisableBcastFlagToggle, and then press ENTER.

5. Right-click DhcpConnDisableBcastFlagToggle, and then click Modify.

6. In the Value data box, type 1, and then click OK.

7. Close Registry Editor.

MORE INFORMATION

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

Note A data value of 0 disables this registry entry. You can use this registry entry to prevent Windows Vista from using the DHCP BROADCAST flag. After you set this registry entry, Windows Vista never uses the DHCP BROADCAST flag.
