This is most likely the Vista issue caused by the Broadcast flag used in DHCP request that is not compatible with many older DHCP servers.

There are a few workarounds.

I would recommend doing the first 2 listed below and reboot the computer first. If this doesn't work, perform the registry modification which is listed below in 3rd item and also the same listed above as a Microsoft suggested fix.

Disable the IP Helper service:

1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
2. Scroll down to the IP Helper service, right click on it and select Properties
3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
4. Then click on "Stop" to stop the service from running in the current session
5. Click OK to exit the dialog

Disable IPv6:

1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter
2. Right click on each network connection and select "Properties"
3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)
4. Click OK to exit the dialog

NOTE: You should do this for each network connection.

Disable the DHCP Broadcast Flag:

Link: http://support.microsoft.com/default.aspx/kb/928233

1. Hold the Windows key and type R, enter regedit and press Enter.
2. Locate and then click the following registry subkey:
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
4. In this registry path, click the (GUID) subkey to be updated.
5. If the key DhcpConnForceBroadcastFlag does not exist, use the Edit menu, point to New, and then click DWORD (32-bit) Value. In the New Value #1 box, type DhcpConnForceBroadcastFlag, and then press ENTER. If the key exists, skip this step.
6. Right-click DhcpConnForceBroadcastFlag, and then click Modify.
7. In the Value data box, type 0, and then click OK.
8. Close Registry Editor.
9. Reboot Computer.
NOTE: You should do this for each and every GUID subkey.
NOTE2: (GUID) is a mnemonic for the individual subkeys, the actual text "GUID" does not appaer.
