I've got the following problem at one of our customers:
They're trying to access their bank account with an application. Lately, their internet connection got lost. This was at the end of the day, so they just waited for the next day, and the internet worked again, except for the SSL and HTTPS connections. They do not work for any computer in the whole network. Sites like hotmail and logging in to the bank (HTTPS sites) do not work. Also an application that's making connection to the bank via SSL ain't working on any PC on the network. Things I've allready tried:
Connecting a Pc direct to the internet (attaching it to the internet modem).
Disabled the Windows Firewall on the local Pc.
I've checked alot on the internet, there are some people with the same problem, but people only suggest r*tarded solutions as: use firefox. empty cache. uninstall antivirus. But it's nothing of that, it's a network problem, not local.
If anyone has a proper solution, please let me know.
Thanks in advantage.
