The monitor service under site server settings installs three components when it installs: RMS agent, Pluggable Protocols Agent, and Credential Manager. On occasion a previous install can cause the service to fail to install with exit code 1603. Primarily this occurs with the RMS agent and/or the Pluggable Protocols Agent.
Error 1603 will be displayed in the task status, task history, event viewer application logs, and agent logs when the failure occours.
The event viewer application logs will generate the following error: Windows installer installed the product. Product Name Monitor Agent for Windows Package. Product version 7.x.xxxx.x. Product Language: 1033. Manufacturer: Altiris. Installation success or error status: 1603. Event ID 1033.
The the monitor RMS package will fail with error:
Product: Monitor Agent for Windows package -- Remote Monitoring Server requires PPA Agent installed. Setup cannot continue. Event ID 10005
The exact cause of this error is unknown, but it is always caused from a previous install that did not successfully uninstall.
The problem is caused by a partial installation, so try to uninstall the monitor service from the Altiris Console. Navigate to Settings > Notification Server > Site Server Settings. Expand Site Management > Site Servers and select the problematic site server. Select Install/remove services. Uncheck Monitor service (note: it may already be unselected because of the partial install, please see next steps). Go back to Settings > Notification Server > Resource Membership Update. From here log on to the problematic server and do a configuration update and see if both RMS and PPA uninstall correctly. If this works try to reinstall the monitor service and see if it fails again.
