I am getting Error 720 on Windows 7 (32 bit) while connecting to internet using DSL as well as USB wireless modem. I tried everything like setting tcp/ip addresses but no luck. Both the connections (DSL and USB) work well on Windows XP. Regards, Sagar Deshpande

The following information @ http://www.tomshardware.com/forum/24752-42-internet-connection-error was found by searching the internet. harvest 12-13-2008 at 03:35:50 AM Show message - 1 + I hunted for months for a solution to this problem RAS error code 720. I have a Thinkpad T60 and about six months ago was suddenly unable to use my Vodafone Vodem so I tried my old Vodafone card modem and it wouldn't work either. Even tried my Sony phone with a cable and it wouldn't work. When I've travelled for the last six months I have had to take my old T42 with me and all the modems work fine with that laptop. I have tried many solutions to this and wasted countless hours. Today I finally found a tiny free program called rarepair.exe - do a search and you can easily find it but I got it from here http://forums.practicallynetworked [...] mentid=131 Click on it and it removes all your network drivers, reboots your machine, reinstalls the drivers and then does a second reboot. Everything was restored perfectly. I would have paid serious money for this as it has saved me from doing a fresh XP install which would have taken weeks to get everything reinstalled. Please copy this to any sites you have visited while trying to find a solution. Microsoft couldn't fix this problem - or pretended it didn't exist. Lenovo are in denial that it exists. The person who wrote this little program is a hero!
