details: what are you trying to connect to and how

Details are

I am using windows xp.I want to connect internet using bsnl dial up connection.I used to connect through bsnl dial up connection.But now a days i cant connect and showing the error message Error 720: A connection to the remote computer could not be established.

What will be the real problem ? Do you know about this ?


error is in network protocols.
try diabling the yellow iconed network problems in device manager.
Then uninstall them
then reboot and reinstall the drivers for that and done.


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


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!


RAS error is a blockage on your laptop it has nothing to do with the ISP or modem settings or router, or your USB modem or aircard

> If its with USB modem or aircard remove the device, remove the cables

> Go to Command Prompt type netsh int ip reset c:\resetlog.txt it will reset your TCP/IP > restart your computer

> try to connect should work.......


Thank you star98m. I usually have this error report on my computer. And your suggestion of over 2years ago on this thread has helped me solve this problem. You are a blessing to near novices like me and may God bless you. Also thanks to sree22_happy for bringing this up on this thread.


Have a question. Does this resolution works for windows 7 OS as well?
