If multiple machines show that the smart scan is not available and the agent certificate verification and check server status for the iCRC scan also fail, the following steps can be considered for troubleshooting:

1. Review the logs for any dated occurrence of the issue on the affected machines. Identify and assess any logged errors, warnings, or critical messages.
2. Take note of System Details, such as Computer Name, User Name, Operating System, and Elapsed Time.
3. Amend the ofcscan.ini file with the below change:

[ICRC_SCAN_INI_SECTION]
CheckScanServerStatusTimeoutMillisec = 8000
