Endpoint Protection

I need to determine if our server has a SCAN Exclusion for Symantec AntiVirus.   Is there a log that will identify the exclusion(s)?  If any?

No but you can check the registry. See this KB article:

HOW TO VISUALLY INSPECT EXCLUSIONS
 

1. Start > Run > Regedit 
    
2. Browse to the registry key:
   • HKEY_LOCAL_MACHINE\SOFTWARE\SYMANTEC\SYMANTEC ENDPOINT PROTECTION\AV\EXCLUSIONS
     Note: On 64bit window machines the registry path is:
     HKEY_LOCAL_MACHINE\Software\WOW6432Node\Symantec\Symantec Endpoint Protection\AV\Exclusions 
      
3. Expand the key to view the various applications listed there.
   • The 'File Exceptions' folder is where you can inspect the full list of exclusions associated with that product.

This key is where both automatic and policy added exclusions are stored on the client. Inspecting this key reveals all exclusions applied to the client. If you do not see the exclusion you are trying to add listed in the registry, then it is not being added automatically. You must manually add it to a Centralized Exceptions policy.
