Why is it not opening? Every damn site is opening, but not this... Neither in FF nor in IE. Shows a 400 error code for it. Tried in my friend's Tata Indicom connection, it opened there and I was able to log-into my account (i.e. my account is not blocked). But, not opening in my system. Contacted Airtel customer care to know if they are blocking it. They told they are not blocking and flushed my MTU. That also didn't do the trick. Is there any possible that KIS is blocking it? Can anyone help me where this site wise restrictions are stored for KIS2009. I got only apps in allowed/not allowed section. No sites are mentioned.
