Windows Forum / Windows XP / Networking and Web / March 2004VPN After XP upgrade
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.

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. >-----Original Message----- >See 271731 PPTP clients cannot connect to a PPTP server that has multiple IP [quoted text clipped - 16 lines] > >. 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. >-----Original Message----- >See 271731 PPTP clients cannot connect to a PPTP server that has multiple IP [quoted text clipped - 16 lines] > >. |
