When accessing LabTutor Server with Internet Explorer, I get a Certificate Warning page without the option to 'Continue to the website anyway'. How do I resolve this?


This issue is caused by Internet Explorer by default no longer accepting RSA Certificates less than 1024 bits in length (LabTutor Server's Certificate is 512 bits in length). As such, the 'Continue' button will not appear unless you modify this setting on your system. To do this, follow these steps:
- Find your Command Prompt shortcut on your computer. If you're on Windows 8, it will sit in your app screen, or if on Windows 7 it will be under Start | All Programs | Accessories
- Right-click the command prompt and choose Run as Administrator (this is known as an Elevated Command Prompt)
- Enter the following command line, and then hit Return:
certutil -setreg chain\minRSAPubKeyBitLength 512
This will reconfigure Windows to accept RSA Certificates of 512 bits or larger. You'll now be able to click 'Continue to Website' when trying to access the LabTutor Server.
