Hello,
This problem is usually related to several factors, including network configuration, permission issues, and so on. Here are some possible resolution steps and checkpoints:
Check your network connection:
Make sure your computer can access the network properly, especially to the target server or computer.
Permission issues:
psloggedon requires sufficient permissions to query other computers on the network. Make sure you have sufficient permissions to access the target computer. If you are in a domain environment, you may need domain administrator rights.
SMB protocol:
psloggedon uses the SMB protocol to query session information on a remote computer. Make sure that both your computer and the target computer support and enable the SMB protocol. In some cases, especially when it comes to newer versions of Windows, SMBv1 may be disabled and psloggedon may require SMBv1. You can try enabling SMBv1 (although this is generally not recommended due to its security risks), or see if a newer version of psloggedon supports a higher version of SMB.
