IP Address Problem in Windows Vista Operating System

[Jalabala]

hi there.........

The trouble I am having is the network card. It cant seem to grab a valid IP addres from my router. It always grabs the internal IP addres of 169.xxx.xxx.xxx with no internet connection. I have uninstalled the drivers and re-installed them. i have turned the on board nic off and tried 2 PCI nic cards drivers for those install fine but still the same problem. I tried running a few winsock fixes also.... no such luck. I have checked the router its working fine. the system is set for auto config of the ip address and does like it should be. Anyone have anymore ideas?

Please suggest few reply on this...........

According to me..........

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.

hi.........
Follow these steps properly:

1. Click Start
   
2. Type regedit in the Start Search box, and then click regedit in the Programs list.
   
3. If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
4. Locate and then click the following registry subkey:
   
5. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
   
6. In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
   
7. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
   
8. In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then
9. press ENTER.
   
10. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
    
11. In the Value data box, type 1, and then click OK.
    
12. Close Registry Editor.
    
13. By setting this registry key to 1, Windows Vista will first try to obtain an IP address by using the BROADCAST flag in DHCP Discover packets.
    
14. If that fails, it will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.

Try this one:

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

Value name: DhcpConnForceBroadcastFlag

Value type: REG_DWORD

Value data: 0
