Hy! I had some problems some weeks ago, trying to find out where and how to set the retry time for DHCP client, the interval that it searches for a DHCPD server. Normaly this interval is set to 5 minutes, so every 5 minutes the dhcp client is searching for a dhcp server, if it hasn't found one. So searching without any result, I've asked the support team from Microsoft, and the replied with these 2 options HKLM\SYSTEM\CurrentControlSet\Services\Dhcp\Parameters "AutonetRetries"=dword:300 OR HKLM\SYSTEM\CurrentControlSet\Services\tcpip\Parameters "AutonetRetries"=dword:300 I haven't had the time to test each of them yet, but if someone needs to modify the dhcp retry time can try these. And maybe reply if it worked or not.
