Altiris Agent is installed on a client computer. Most of the subfolders under C:\Program Files\Altiris\Altiris Agent are created. 

The Altiris Agent Service is also installed. However, the Altiris Agent Service starts for few seconds and then stops. If you try to start it manually, the following error appears:

Could not start the Altiris Agent service on Local Computer
Error 1067: The Process Terminated Unexpectedly 

Even though I remove and reinstall the Altiris Agent, it doesn't make a difference.

Looking under the Agent log, you can see the following:

"10/25/2007 12:13:50 PM","Client Thread thread 0xCAC beginning"
"10/25/2007 12:13:50 PM","Error reading policy from file C:\Program Files\Altiris\Altiris Agent\Client Policies\ServerName.Domain.com.xml: Error loading policy file: The system cannot find the path specified. (-2147024893). This is normal the first time the agent runs after being installed."

"10/25/2007 12:05:50 PM","Loading client object: Altiris.SWD"

The Log will stop suddenly after the above line (Altiris.SWD). New entries will be a repeat of the startup process.

Looking under AeXNSC.log, the following is noticed:
