Q: When navigating to a website in Internet Explorer, I get a warning that the certificate of the site is not trusted--but why don't I get the option to ignore the warning and continue?
A: The most common cause of this problem is if the certificate is using a key length of less than 1024 bits--it's rejected and blocked by newer versions of Internet Explorer.
You will typically see this on hardware appliances that have a built-in website. One option to try is to reduce the required key length to 512 by running the command below from an elevated command prompt:
- certutil -setreg chain\minRSAPubKeyBitLength 512
