Deploy Agent with Bat/PowerShell Script

• Please navigate to "Group Policy Managment" and create a new GPO under the OU.

• The GPO name can be "CyberCyte_Installation".

• Under the "Scope" -> "Security Filtering" add Domain Computers and Domain Users.

• Right-click on the GPO and select "Edit".

• The "Group Policy Managment Editor" will appear. Please navigate to "Computer Configuration" -> "Policies" -> "Windows Settings" -> "Scripts (Startup/Shutdown)".

• Double-click on the "Startup" and add the script. The script can be .bat format or .ps1 format, it is optional. Please make sure the script location is under the default script path, e.g:“\\dc01\sysvol\domain.local\scripts\install.bat”.

• Also, please upload CyberCyte package under the default script path, same as the startup script. The script and the package should be in the same directory for proper installation.

• Click "Apply" and exit.

• Run "gpupdate /force" in CMD.

• The machines should get the policy after the next startup.

• For execution logs, please navigate to "C:\ProgramData\ ". The logs will appear after the startup script execution.

Additional Configurations and Troubleshooting

• Please make sure the startup scripts are always wait by default:

• Please navigate to “Computer Configuration” → “Policies” → “Administrative Templates” → “System” → “Logon”

• Set “Always wait for the network at computer startup and logon” = Enabled.

• We can edit the delegation if it is required Click on the GPO and navigate the Delegation section.

• Click the advanced button. Then select the user, computer or group. Give the read permission. Read permission is enough.
