Vista can’t get IP Address

Yes Vista is getting quite old now but I have many clients still on this operating system and for a couple of them I was stumped on one issue, no ip address.  No matter what I tried I couldn’t get a connection, eventually I would manage a LAN connection but never wireless and its a bit of a bind if the system is a laptop.

Well recently I had to format and reinstall a Vista laptop and guess what no connection, both cable and wireless would be off.  After much trawling I came across this snippet.

“To resolve this issue yourself, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:

Click Start

  1.  Start button

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

     User Account Control permission

    If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.  

  2. Locate and then click the following registry subkey:

    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 DhcpConnEnableBcastFlagToggle, and then press ENTER.
  5. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
  6. In the Value data box, type 1, and then click OK.
  7. Close Registry Editor.

I followed the steps above and whoopi do all the connections worked.  As far as I know this affects all versions of Vista including  Service Pack 2.
