GlobalProtect connection issue after disable windows auto startup

[BennyLam]

Hello experts,

I am going to deploy GlobalProtect to large amount of laptop by Windows script and modifying registry. However, I am able to disable the auto-startup function but unable to establish the VPN after launch the GlobalProtect execution file. Any ideas? Here is my deployment steps:

1. create a GP shortcut in laptop desktop

cd C:\Program Files\Palo Alto Networks\GlobalProtect
copy PanGPA.exe %AllUsersProfile%\Desktop\

2. change the GP portal address by registry

reg add "HKLM\SOFTWARE\Palo Alto Networks\GlobalProtect\PanSetup" /v Portal /t REG_SZ /d "<domain.com>"
3. disable the auto startup after windows login by registry

reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /v GlobalProtect

4. launch the desktop PanGPA.exe but unable to establish the VPN, Display "Connection failed" message

If I do not run the step 3 and 4, the VPN can be established.
