This document describes why the device configuration preview feature in Cisco Security Manager (CSM) might fail to work correctly.
When I preview a device configuration in CSM, why does the window immediately disappear?
This issue might be caused by a user permissions issue on the CSM server.
The Cisco Security Manager service runs as the user casuser, and that user must have local administrator privileges for the CSM to run properly. If the casuser user does not have write permissions to certain folders in the CSM installation directory, the device configuration preview feature might fail to work correctly. For more information on the user accounts used by CSM, refer to the Understanding the Required Server User Accounts of the Installation Guide for Cisco Security Manager 4.0.
In order to ensure that the casuser account is assigned the required permissions on the system, use these instructions to reset the casuser user account:
In order to reset permissions for a user, run this utility:
This utility uses the casuser password and modifies permissions for the ID that CSM runs as casuser. This utility must be run with administrator privileges and is the same program that originally sets the permissions during installation.
