Hi,

I am receiving the following error on my Windows XP SP2 (Lenevo T60p)

Error 720: A connection to the remote computer could not be established

I a unable to connect using dial up connection. However the same connection works if use some other PC. Is there a way to resolve it.

It verifies the username/password then during negotiating protocols it seems to fail. I tried verifying setting amongst diferent systems, they are same, but still it doesnt works on my laptop.

Thanks a million :)

You may need to speak to the ISP as well if they have anything special being used.

But this is a security related issue so look at what is different on this unit as apposed to the others.

It doesn't seems like a security issue, since I am able to use other machine to connect to network using the same hardware, logon credentials.

Still I talked with ISP, they said check with your hardware vendor. And Hardware vendor was unable to determine any problem with drivers or hardware. And he suggested the unwanted method of format and reinstallation which I don't want to do.

Not Domain or Network Settings but the Security Settings on the IBM Think Pad.

There will be something in there that is different to the remaining hardware that works.

Yes I did followed that procedure. But it still gives the same error.

Well I don't see any other security software installed on my laptop (Except Norton Security). I tried after disabling it too. Still the same error.

Open IE and look at the Security Settings in that or if you are using a different Web Browser you can open that and do the same thing in there.

In IE it's under Tools then Internet Options and may be some of the easier ones are in Outlook which are connected to IE.

Go to control panel, add remove progs, windows components uncheck networking
Reboot
do same as above this time check networking
Run cmd, type these and press enter
"netsh int ip reset reset.log"
Enter
"ipconfig /flushdns"
Enter
