Description of Issue

The server agent will not come online or will not install on a Server or Workstation that has threat protection enabled

Cause

The issue affects customers that use a threat protection product on their Active Directory servers where the agent is installed, and that threat protection detects the Quickpass process as an unidentified process, blocking it from running. 

Resolution

   C:\ProgramData\Quickpass Software
    
   And whitelist if possible the service:
   
2. You can also whitelist the signature file for the installation file

ThreatLocker

ThreatLocker has a policy called “RunDLL - Block Internet (Ringfenced)” which is by default applied to each workstation and server group. This policy needs to be updated to allow the FQDN in the INTERNET ringfencing.
