Patch Tuesday will take down your phonesystem…

Its a while since patch Tuesday has taken down any communication system. For those who can’t remember, Skype went down because of this. Now it is Microsoft to learn a lesson. The patch KB974571 “Vulnerabilities in CryptoAPI could allow spoofing” will actually render your Microsoft Office Communications Server useless. It will think that you will just have a demo license and then stop. Luckily it should only be to uninstall the patch and you are up and running again. Tom Keating has more on the topic.
