When I try to connect, I get the error "Disconnected. Error 721: The remote computer did not respond." Here is the strange part: The remote PCs can successfully dial out to another server using VPN. Similarly, error 678 vpn I can successfully dial into the central site from my work PC. The remote computers are dialling out through a Netgear DG834Gv4 (latest firmware), and the server is behind a Draytek 2820. I have also tried using the Draytek as the VPN endpoint (instead of it doing pass-through), which again worked successfully from my work PC, but gave the same result from the remote site. I can ping the central site from the remote one, no problem. I can also telnet into port 1723 from the remote site. The central server is a domain controller with AD. At some point in the past, the remote PCs were successfully logged onto the domain, so now log into that (but obviously can't connect). The remote PCs are on a network which contains another SBS 2008 domain/domain controller/AD/server. However, the remote PCs are using the DG834 as their DNS/DHCP/etc. I and my colleagues are totally stumped - we know each end is fine independently, but for some reason they won't work together. We don't think that it's authentication; it doesn't seem to get that far. There's nothing in either router's firewall which would prevent one the remote IP but not my work IP. The MTU of the DG834 has been changed to match the Draytek. Any ideas? vpn pptp share|improve this question asked

When I try to VPN in from another location using a Windows server 2003 I lets me then it tries to verify username and password, it takes about 60 seconds and then comes back with "Disconnected Error 806: a connection between your comuter and the VPN server has been established, but the VPN connection cannot be completed.
