The remote agent installation failed to complete.
This can be caused by various reasons.
Check the agent management installation logs to determine what failed. Under the Management Server install directory there is a folder for failed agent installations. The installation logs may provide enough information to determine what failed. The installation logs are located in the AgentManagement\AgentLogs sub directory of the installation folder. Example using the default installation paths:
System Center Operations Manager
%ProgramFiles%\System Center Operations Manager 2007
System Center Essentials
%ProgramFiles%\System Center Essentials 2007
Open the event log on the target computer where you were attempting to remotely install the agent.
Look in the Application and Security event log for any errors that may indicate why the Management Server was not able to remotely install the agent.
Fix the errors.
