Guest David Posted November 7, 2007 Posted November 7, 2007 I did post this in the SBS group by mistake. It isn't an SBS Network. Hi We have several hundred remote users. It has come to my attention that when they VPN in they don't update their DNS records automatically. This can only it can be done by running the ipconfig /registerdns command. We have a RAS server on the network and two DHCP servers which assign the clients IP addreses. Both DHCP servers are relay agents for the RAS. I have checked DHCP and it is set too "Always dynamically update A records and PTR records" both on the server level and on the scope. I think the problem maybe that a computer only registers its DNS when it starts up, and when they initialise the VPN to the office it doesn't. On the properties of the VPN connection i have selected the option to "regsister this connection in DNS" but still no joy. We have a firewall on the network which just passes through PPTP connections straight to the RAS server. I came accross an article on the internet that the firewall could block UDP packets, but as the VPN establishes then i wouldn't think this as a problem. Any ideas. If you need anymore info i will do my best to get it to you.
