Hello, I am planning on implementing a Windows client to server VPN using RRAS and IAS:See postWe are running a medical app that uses network discovery to check for a network key on one of three servers located in the office.The s/w company is disinclined to say how key discovery is performed because they do not want people tinkering with it.When users bring their Laptops into the LAN, they can open the medical app because the key on the server supports 5 concurrent users. The application discovers the multiple servers automatically and checks that a network key license is available.In need the VPN to allow all ports to be open and broadcasts enabled, just like if the client was inside the LAN. Are broadcasts like NBT able to traverse the VPN tunnel?Any help is appreciated. Naki K. / Falcon ITSComputer and Network Service and Support, Miami, Fl

Hello, Thank you for your post here. Yes, you can make NetBIOS broadcast name resolution available between VPN server a d VPN clients. There is a option "Enable broadcast name resolution" in the RRAS MMC. If you enable it, a remote access client can resolve full computer names and NetBIOS names of computers and other resources on a remote network that does not have either a DNS or a WINS server configured. However, the configuration is not recommended because it breaks the broadcast domain between the networks.

Thank you Miles. One last question, if I enable this option, once the client disconnects, the broadcast domain will revert back to his/her local network? NakiNaki K. / Falcon ITS Computer and Network Service and Support, Miami, Fl

Hi, Yes, the option "Enable broadcast name resolution" will only work between the VPN clients and internal network where VPN server resides in.

Dear Miles Li, Could you give some solution with VPN Server? In my comapny using Windows 2008 Server as: ADDS, DNS, Exchange Server, and so on!
