The exhibit shows log entries from the FSSO (Fortinet Single Sign-On) collector agent logs. These logs provide insights into why there might be issues with the collector agent connecting to workstations or the registry.

Remote registry is not running on the workstation: The failure to connect to the workstation registry can occur if the remote registry service on the workstation is not running. This service needs to be active to allow the FSSO collector agent to query the workstation for user login information.

DNS resolution is unable to resolve the workstation name: The logs indicate a failure in connecting to a workstation by name, which can happen if the DNS server is unable to resolve the workstation's name to an IP address. This is a common issue when the DNS settings are incorrect or the workstation name is not properly registered in the DNS.

A firewall is blocking traffic to port 139 and 445: Communication issues to the workstation or registry are often caused by firewall rules blocking essential ports. Ports 139 (NetBIOS) and 445 (SMB) are critical for these operations. Ensure these ports are open on both the workstation and any intermediate firewalls.

The session table entry provided shows detailed information about a specific network session passing through the FortiGate device. From the session details, we can see that the session has various attributes such as state, protocol, policy, and inspection details.

The session state (proto_state=11) indicates that the session is being actively processed and inspected.

Thenpd_state=00000000suggests that the session is being handled by the CPU rather than offloaded to a Network Processor (NP).

The session is marked for security profile inspection, evident from the detailed byte/packet counts and other session parameters.

From these indicators, it's clear that FortiGate is using its CPU to perform security profile inspection on this session rather than simply forwarding the traffic without inspection or relying solely on IPS inspection.
