WebHost Failed to Process A Request – Reach Service does not exist

While working on a new Skype for Business Server 2015 Enterprise Edition Pool, a colleague of mine noticed an error on just one out of the 12 servers…

They were all deployed at the same time, all had Windows Update ran with the same number of patches, and all had the same Skype for Business Server CU installed.

The Problem Server

Only 1 of the Front End Servers had logged the following event numerous times to the Application Event Log.

The Fix

He uninstalled the “IIS URL Rewrite Module 2”, and “Skype for Business Server 2015, Web Components Server”, and re-run¬†Skype for Business bootstrapper (Step 2 in the Deployment Wizard).

Cheers Joseph, good work spotting that.
