Hi All,

Recently I was reinstalling the WSUS server role on Windows Server 2012 R2 , I was able to remove the role and then install the role through server manager without any problems.

However, when I came to launch the ‘post installation tasks’ from server manager, the task was repeatedly failing and I was not able to open the WSUS configuration wizard.

To fix this, I removed the role once again, opened¬†IIS and deleted the site ‘WSUS administration’ which still remained when the role was not installed. After reinstalling the role, the post installation tasks completed successfully.

Hope this helps!
