I am experiencing the same issue described in:http://social.technet.microsoft.com/Forums/en-US/itprovistanetworking/thread/14200a64-3922-4395-9f80-9f293808395a/ Running Vista SP1 and Windows 2008 SP2 and attempting to use classless static routes DHCP option to enable split tunneling. I've set the registry keys in (http://support.microsoft.com/Default.aspx?id=933340)and confirmed the dhcp binaries are indeed SP1 or newer.Has anyone found a working solution to this?Thanks!

Hi, Thank you for posting. From your description, I suspect you have more than one internal network segment locally. For a clear understanding of this issue, could you please provide more information about the topology (IP addresses assignment) of your network? If you have enabled the DHCP class ID to isolate the VPN client from the internal clients, please disable it and check how it works. To narrow down the issue, you may check how it works if you simulate a remote VPN client in your internal network. If the issue persists in this scenario, you may take a network traffic trace on the client for further investigation. To do that: 1. Download the Microsoft Network Monitor 3.3 from the following link: http://www.microsoft.com/downloads/details.aspx?FamilyID=983b941d-06cb-4658-b7f6-3088333d062f&displaylang=en 2. Install the network monitor on the internal client that simulates a remote VPN client and start to capture. 3. Dial the VPN connection to reproduce the issue. 4. Stop the captures and save the network trace files to verify the process how VPN client requests the option 121. You can use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the file and share its URL with us for further investigation. Meanwhile, I would like to share the following document with you: [MS-DHCPE]: Dynamic Host Configuration Protocol (DHCP) Extensions: Product Behavior http://msdn.microsoft.com/en-us/library/cc227315(PROT.13).aspx If you have any questions or concerns, please do not hesitate to let me know.
