I have Lync Server 2013 running on Server 2012 R2. All of a sudden the Lync Server Control Panel isn't loading anymore. Attached is an image of the error
I am getting HTTP Error 404.4-Not Found page.
Detailed Error Information
Handler: not yet determined
Error Code: 0x8007007b.
I have been able to log in just fine in the past but when I tried the other day I am getting the error. I have verified that Lync is 100% up to date as of now. I looked through the event log and haven't found anything that would point to an error. I'm sure it is a setting somewhere in IIS but I cannot find where. Someone please help
