This week was patch Tuesday for Microsoft, the regular once a month release of all the security updates contains a patch you should NOT install if you want your group policies to run normally.
Apparently this patch breaks any security filtering set in group policies, meaning mapped network drives, printers and a whole swag of other settings will no longer apply correctly to your computers 🙁
We have blocked this patch from applying to our maintenance customers, if you manage your own patches you’ll need to block that manually yourself as soon as possible.
