Keep in mind, there is a chicken and the egg thing going on here with initially joining a machine over a VPN and logging on, and allowing the new domain account profile to initialize. This is a good discusion with specifics about how an IP config is passed to a RRAS client and DHCP relay agentsĬonfiguring the DHCP Relay Agent to Support VPN Client TCP/IP Addressing Optionsĥ. Thread Discussion: DNS DHCP option 006 not being applied to VPN clients via RRAS Understanding DHCP IP Address Assignment for RAS Clients Configure a DHCP Relay Agent to insure DHCP Options are provided to VPN clients, otherwise they will get the VPN server’s WINS and DNS addresses, and they will not get any other options, such as Option 015, the Connection Specific Search Suffix.

I always mention this to prevent AD issues. This is a very common misconfiguration due to an admin not understanding AD and its DNS reliance. The reason I’m stating this right off the bat, is if using your ISP’s DNS configured on any internal machine’s NIC DNS settings, is inviting trouble. You can configure your ISP’s DNS as a Forwarder. This means do not your ISP’s DNS servers, or use your router/firewall as a DNS address. First, I must state as a rule of thumb, that all of your internal domain controllers, member servers, and clients are set to only use the internal DNS servers, more than likely your domain controllers.
Let me know if any of these steps are not clear or if something else needs to be added that I may have missed, and I’ll do my best to integrate or clean it up.ġ. I’ll configure the laptop, then either ship it back, drop it off at the main office, or someone will stop by to pick it up. Normally, I would visit the office to setup a new laptop, but in some cases, such as with one of my customers with 90% of their users are on the road in various parts of the country, they’ll either have the new laptop shipped to me, or they will ship it to me once they’ve received it, or someone local will drop it off to my office.
