Today has been one of those days where you think to yourself. “Self, you should have backed up your data more often!” My work laptop running Windows 8.1 decided to commit suicide.

The problem is that we use Bitlocker which meant it would be a challenge to just boot up with a Live Linux Distro and copy off my needed data. After a few hours I managed to access my…

Outlook Web Access stops working after renewing 3rd party Certificate

After a long investigation we found the issue to be ISA running on Windows 2003 which is not compatible with the Secure Hash Algorithm 2 (SHA2) family of hashing algorithms that the certificates from our 3rd party cert provider issues. Microsoft has a hotfix available to get around this. We were able to access OWA from the internet…
