http://support.microsoft.com/kb/928233 Very nice solution Microsoft, and actually it works when I change the DhcpConnEnableBcastFlagToggle to 0. But - I have 400 vista clients in my network, and i'm not planning to do this manually on all of them.. I can't see how I should resolve this by a GPO because the GUID key in uniqe from client to client. So how do i disable the DHCP broadcast flag in windows vista on 400 clients at the same time?
