<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I have built ISC DHCP 4.2.3-P1 on Centos 6.2. I am trying to use a Windows 7 client to obtain an IP Address as well as DNS information from the DHCPv6 server I setup. I am
currently unable to get my client to ever respond with an Information-Request. I can see the Solicit and Advertise messages hit the server and with wire shark I can see that the server is handing the client all of the information I have configured in my dhcpd.conf
file. I have configured the M flag on my router to inform the client to use the DHCPv6 server for it's informaiton. Are there additional steps that I need to take to get the client to accept the information from the server? </span><o:p></o:p></p>
