Lync Control Panel 404.4 Error
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 errorI am getting HTTP Error 404.4-Not Found page.
Detailed Error Information
Notification:MapRequestHan dler
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

When I try to load https://localhost/cscp on the local server I do receive the same error page.
When you open IIS.. can you check if CSCP virtual directory exists or not?
Also open event viewer and check under the Lync logs if there any recent errors .. please post their event numbers here for the last 10 error events

Have you assigned a certificate ?? Can you please post a screenshot of your IIS binding of the port 443?
Also on CMD run the following commands and post the result here
Netstat -anbo >ports.txt Enter
notepad ports.txt Enter
Post the ports result here.

Yes I have a certificate assigned. Where do I pull the screenshot for the IIS bindings of port 443?
So a little history on what may of broken the control panel, I was trying to get lync to work on mobile internally only. I don't care about it working outside of my company only internally on our wireless. In trying to set it up I was attempting to setup a reverse proxy in IIS. I ended up getting other errors so I removed all the settings I changed and this is when I noticed that the control panel wasn't working. Not sure if control panel had been offline before this or if my changes effected something somewhere.

IIS rewrite 2 is normally not installed on Lync front end as far as I can remember. it's installed on the IIS ARR server which is considered a reverse proxy for lync's mobility feature.

I was able to google more into the issue and found the solution but with assistance from Mohammed
