After installing the patch, I have suddenly had issues with OWA and Activesync not working proper;y. I have been able to narrow it down to IIS converting to 32 bit and was able to get OWA back up by converting it back to 64 bit but there are still issues with contacts and calendars tabs. Also I can't change the authentication in ASP.NET. It seems to be stuck on forms based and won't allow me to change it since the tab went missing. I was able to get the tab back but when it reappears it is empty. Anyone see something like this or know how to fix this issue?
