A friend asked for information: Open HTTPS page under IE9 always appear "This site security certificate has a problem", click "Continue browsing this site (not recommended)", but always can not jump to the next link, encountered such a problem, how to directly access the HTTPS page?

Look at the problem:

1, Windows 7 system IE9 VPN site (SSL VPN), cannot open

2, the same SSL vpn,windows XP IE8 can be opened

The ranger suddenly thought of the previous company's internal mail, mentioned Microsoft's KB2661254 patch, the effect is: the patch on the HTTP SSL certificate minimum key length limit, no longer allow less than 1024bit certificate connection, may cause some devices can not use IE login.

Microsoft's description of KB2661254 is:

After you install this update in your Windows system, you can keep your system up to date by elevating the minimum encryption level. After you install this update, you may need to reboot your system.

The ranger searched the search engine, found that some people (although not many) raised this question, and are in KB2661254 issued after the release, there are reasons to think that almost all of this problem, the solution is very simple, any one can:

Method One: On the computer accessing the HTTPS page, uninstall the KB2661254 patch. Recommended

Method Two: Upgrade the SSL certificate length to 1024 bits, the equipment, may contact the factory to solve.
