Unable to connect to VPNI have been unable to connect to my office VPN from my Laptop from home
to work using Microsoft VPN Client. This has worked for me from my laptop in the past but one fine day it stopped working. I am able to connect using my Desktop at home. The dialog box "Verifying Username and Password ..." times out with Error:721. I have checked all the preferences and have tried disabling the firewall etc. and have been unable to get past this issue. Any help will be greatly appreciated... It could be the GRE issue. I would upgrade the firmware on the router first.

Still have not been able to connect to VPN. I use
a Netgear WGR614v4 Router/WAP. My desktop is also using the same wireless access point and it works from my Desktop. Is there a way I can uninstall/install just the VPN component in the Microsoft TCP/IP stack? Robert L [MVP - Networking] wrote: Show quoteHide quote > It could be the GRE issue.
