SEP 11.x error message "Scan Failed: Scan failed to start"
I installed recently Symantec Enpoint Protection 11.x unmanaged client. Everything seemed to work except when trying to scan from "Scan for Threats". Nothing happens when clicking on Run Active Scan or Run Full Scan. Creating a new scan to be started on demand and executing it by right-clicking and selecting "Scan now" yields an error message - "Scan failed: scan failed to start". There is no mention of this error in the Logs. This error does not happen in Windows XP Pro SP3 Safe Mode.
Has anyone seen this error before or has any recommnedation on how to solve this problem? Uninstalling and reintalling SEP and using CleanWipe did not help.
