Does the Airport Express support the DHCP BROADCAST flag

Question

In trying to connect a vista laptop to an existing Airport Express Network and the internet, went ot MS Help and found an article saying Vista is set with a 0 (Zero) in the Registry (whatever that is).The comment is -
A 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.
Can someone who doesnt type in UNIX or DOS tell me what might work and if this even applies. I am not inclined to do the following -
Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or for confirmation, type the password or provide confirmation. 
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.
On the Edit menu, point to New, and then click DWORD (32-bit) Value.
In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.
Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
In the Value data box, type 1, and then click OK.
Close Registry Editor.
Hard wired to the Cable Modem the computer can connect to the internet without any of this. What in the Airport Express could be blocking this computer?

Sorry, none of the Apple products support this.
