Reinstalling SQL Reporting Services for Systems Centre Operations Manager 2012 (SCOM)

I recently had to reinstall the reporting component of Systems Centre Operations Manager. 

 

On uninstalling the reporting component I subsequently was unable to connect to the SQL instance of the reporting services that we were using for Systems Centre Operations Manager.  On examining the event log I came across the error message of

"Report Server (MSSQLSERVER_ cannon load the Windows extension"

  After some research I found the solution was the run the Resetsrs that can be found on the Systems Centre Operations Manager CD under SupportTools\AMD64\ResetSRS.exe

.  This resolved the reporting service instance problem and was able to re-install the reporting services module.
