I have a brand new laptop with WinXP sp1 that I am
attempting to connect to my corporate network that is
running Win2k server. When I attempt to connect I receive
an "error 721, the remote computer did not respond."
message. My connections passes through a wireless network
in my home and then out over DSL connection to the
internet. I can make the VPN connection from a Win2k Pro
computer at my home but I am not able to connect from the
WinXP machine.

Any suggestions to correct this would be greatly
appreciated.

The connection coming into the network passes through a
Cisco 1600 router and a Netscreen firewall before getting
to the server. The server has only one NIC with just a
single internal IP address. The firewall is set up to
open port 1723 to PPTP traffic.

Why would I be able to VPN in from a windows 2000 pro
computer that is using the exact same route but not the
WinXP Pro?

Marc,

I created the registry key as instructed in the article.
I also tried adding NDS and WINS server entries in the
VPN connection properties. I also added an LMHOSTS record
pointing to the servers. I still get the error:721, the
server is not responding" message.
 
Well, I see all my Technet PLus subscrition gets me is a
two line standard response from the folks at this managed
newsgroup.

The "multiple IP addresses on the server" was not even
close. My subsiquent replies after that response brought
no further help from Microsoft. Thanks guys.

I did find some help on the Google groups. There I found
some postings that suggested the problem lie with the
Linksys Broadband Router that I had installed. While
being able to successfully connect via VPN when I used an
ethernet port on the router I was not able to make a VPN
connection using the wireless LAN on the Linksys. It
seems Linksys firmware for the WRT54G has problems doing
VPN when 802.11b is on the client machine. I fixed my
problem by replacing the WRT54G router (802.11g) with a
BEFW11S4 router (802.11b). Linksys doesn't claim to have
any issues with downward compatability but the proof is
in the pudding.

Thanks again to the MS folks for all their help.
