Can't connect to VPN on windows server 2003
I'm trying to connect to a VPN server (2003) with a Windows 7 installation. Here are some relevant facts* I can connect to the VPN server with XP and Vista, over the same ISP and from behind the same router.* When I make the connection in Windows 7, the computer thinks it's connected (there are no errors and the tray icon says I'm connected).* When I run ipconfig /all, the values returned are reasonable except that there is no "Connection-specific DNS suffix" or "Physical Address" for the the PPP adapter.* I can't ping the DNS server by IP address. The error returned is "General Failure"* ping -a xxx.yyy.zzz.ttt does show the name of the computer I'm pinging.* I tried disabling the firewall andturning off IPv6 to no avail.Does anyone have any ideas of how I might debug this situation?thanks,marco

Hi Marco,
Thank you for posting.
Please try the following:
1. Go to Control Panel\Network and Internet\Network Connections.
2. Right-click the VPN connection and click Properties.
3. Switch to Networking tab, click Internet Protocol version 4 (TCP/IPv4), and then click Properties.
4. Click Advanced, click to select the Use default gateway on remote network check box, and then click OK.
Meanwhile, I suspect you may need to check the DNS settings and I would like to share this document with you:

Thanks. I've made some progress.
If I disable the "use default gateway" I can ping the DNS server using it's IP address which I could not do before. Name resolution is still broken as I can't refer to any computer (even the DNS server) by name. That is (names changed, addresses are real):
$ ping -a 169.254.100.2
Pinging foo.bar.com [169.254.100.2] with 32 bytes of data:

$ ping foo
Ping request could not find host foo. Please check the name and try again.
$ ping foo.bar.com
Ping request could not find host foo. Please check the name and try again.
Again, I the VPN connection works perfectly under XP and Vista.
Any more clues?
thanks,
marco
