I am in need of serious help for the error that I am getting. I am getting that on Vista. The problem is due to forbidden ssl client. I am using a Vista laptop and suddenly started getting this error. I am not able to understand the problem behind this. It is a bit complicated to get through this. I tried to reconnect the network a number of time but still it is not working. I think there is some major hardware bug with the system. Does driver update is capable of fixing the problem.
