When newer versions of IE won’t let you forcibly accept an SSL cert, only allowing you to close the tab, here’s an answer that’s working for me here: https://social.technet.microsoft.com/Forums…
1. Go to “run” -> gpedit.msc
2. Under Computer configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel
3. Under Prevent ignoring certificate error (set to disable even though it’s set to undefined).
This is helpful if you are accessing devices that use SSL right out of the box. Normally, I’d use Chrome or another browser, but sometimes you run into something that’s IE specific… like an older Dell IPMI interface, or the like.
