I have a number of financial sites (banks, credit cards etc) bookmarked where I obviously have to log in.
Occasionally these display "Page cannot be displayed"; it happens to all of them at the same time as I can access any other internet site. I presume the problem is to do with security settings on my PC ( I have NIS 2004).
The problem is solved by doing a System Restore but clearly something is causing this error.
It occurs intermittently and I have not changed any settings before it happens.
Any suggestions please?
