VPN PPTP Problem

[kailash7]

Hi,

I'm having this problem since a few weeks now and just can't get
around it.

I have WinXP SP3 on two laptops. I can use VPN PPTP to connect to a
particular server on one laptop but not on the other.

The problematic laptop gives me a message error 628: The connection
was terminated by the remote computer before it could be completed.
For further assistance, click More Info or search Help and Support
Center for this error number.

I tried reinstalling WinXP on this laptop and the VPN worked fine on a
fresh install of windows only to give the same problem again after a
while.

Anyone ever had the same weird problem? I don't think its related to
firewall since it works fine on the other laptop and i disabled all
desktop firewalls on both PC.

Helppp!

Thanks

Its in fact a trojan that's blocking the connection:
Trojan.Win32.Delf.arn
