Prognosis Skype for Business Toubleshooting Guide

Errors will be displayed in the main window after "Apply Configuration" is pressed if something goes wrong. Most of the time, checking the configuration inputs and attempt to apply the configuration again would fix it. Other errors will require access the machine to fix the issue before attempting the configuration again. Below are the most common errors.

                Failed to stop service: irService.exe


Cannot stop relevant collectors when reconfiguring:

  • irmsmgs.exe
  • irsfbcsm.exe
  • irsfbcol.exe

Files in the RabbitMQ database are missing. When it complains that any file found in:

Please consult the following section of our troubleshooting guide:

RabbitMQ binaries will need to be re-added by

                ENOENT: no such file or directory –  .erlang.cookie


Complaint that file ".erlang.cookie" is missing.


RabbitMQ requires the presence of the erlang biscuit to start, as well as for any commands being run on it. In 11.5 with the upgraded version of Rabbit the default location will be:


If this file does not exist, create a plain text file named ".erlang.cookie". Restart RabbitMQ and it will load this file.
