Everyone writes something about Windows 7 in these days but i want to talk about a problem of Windows Vista.To get an ip address for wireless adapter from certain routers or from non-microsoft DHCP servers if you use Windows Vista operation system.
Our DHCP server is a linux ubuntu in our company and when i got the first windows vista i realized that I cannot get an ip address from DHCP.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.
To resolve this issue, disable the DHCP broadcast flag in Windows Vista locate and open the following registry key:
You can use “getmac” command at the command prompt to find right network adapter.
In these registry key you should also see another Dword value DhcpConnForceBroadcastFlag
set this registry key to 0 and at the command prompt type “ipconfig /renew”
