I have a client who claim they cannot access their internal website when they have e.g. been out traveling. They have to reset their browser settings every time to be able to get access again.
As they live on another continent and timezone it's hard for me to run live tests with them to see what changes in their browser settings.
My first guess would be it's some sort of Proxy related issue, but I want to know if there could be other reasons for this?
It's not the LAN itself, that we are sure of. It's browser specific only.
It's worth mentioning that it only happens when they turn off/restart their computers.
