Title
Agent splash screen hanging at login when system is offline -
Description
When an agent is installed on a system which is operating off the network, the agent splash screen can take a minute or more to load.
-
Cause
The agent is not able to reach the appliance to check in because the system is not connected to a network. The agent installation changes the registry key at HKLM > Software > Microsoft > Windows NT > Current Version > Winlogin from C:\WINDOWS\system32\userinit.exe to C:\WINDOWS\System32\KUsrInit.exe.
-
Resolution
To resolve the problem:
1. Install the agent using the NOHOOKS=1 option at the command line to prevent the Winlogon registry key from being overwritten. Example: msiexec /qn /i ampagent-5.5.25198-x86.msi HOST=k1000.kace.com NOHOOKS=1
Or:
2. Backup the registry key at HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > Current Version > Winlogin (Reference: http://windows.microsoft.com/en-us/windows7/back-up-the-registry} and manually change the Winlogon registry key from C:\WINDOWS\System32\KUsrInit.exe to C:\WINDOWS\system32\userinit.exe (the system may need to be in Safe Mode to accomplish the task).
This resolution is confirmed on 32 bit and 64 bit clients.

Additional Information
NOTE: The reprocussion of the agent not running at startup is Managed Installations set to run "Execute before logon" or "Execute after logon" and Offline Scripts set to "Also Run at Machine Boot Up" or "Also Run at User Login" will not run after modifying the registry key.
