Issue/Introduction

Steps to reduce disk space used by the App Control Server software

Environment

• App Control Server: All Supported Versions
• Microsoft Windows Server: All Supported Versions

Resolution

1. Verify the App Control Server meets the minimum disk space requirements.
   • Server Documentation > relevant Version > Operating Environment Requirements > Server Architecture by Endpoint Count
2. Reduce Policy Installer requirements:
   1. Log in to the Console and navigate to Rules > Software Rules > Policies.
      • Delete any outdated or unneeded Policy.
      • Agent installers are generated for each Policy, which can contribute to required disk space.
   2. Click the link: Click here to view available Agent/Rules Versions (https://ServerAddress/InstallerVersions.php
      • Verify only the Platforms (Windows, macOS, Linux) used contain Agent versions.
      • If a Platform is Enabled that is no longer used, navigate to https://ServerAddress/shepherd_config.php and disable the relevant Property:
        • GenerateWindowsInstaller
        • GenerateWindowsHostGroupZipPackage (used for XP/2003 installers)
        • GenerateRedhatInstaller
        • GenerateMacInstaller
3. Log in to the application server as the Carbon Black Service Account
   • If an Agent is installed, temporarily disable Tamper Protection.
4. Temporarily stop the App Control Server and App Control Reporter services.
5. Delete all temp files in the user profile temp folder (skip any files currently in use):
   • C:\Users\<SERVICE ACCOUNT>\AppData\Local\Temp\
6. Delete (or move) any old/outdated IIS Logs, by default these are in

   %SystemDrive%\inetpub\logs\LogFiles

7. Delete (or move) any old/outdated App Control Server related files (C:\Program Files (x86)\Bit9\) for:
   • Server and Agent Diagnostic Logs: \Parity Server\Support\
   • Archived Event Logs: \Parity Server\ArchiveLogs\
   • Uploaded Host Files: \Parity Server\files\
   • Old Policy Installers: \Parity Server\hostpkg\<VERSION>
   • Temp Policy Installer Files: \Parity Server\hostpkg\temp\
8. If the database is also on the C drive, follow steps to free space in the App Control Database.
