PowerShell script is triggering the AD alert when executing on any local server. as user or computer

Hello All,

I have PowerShell script which generates the data from each local server. This script tested and its working fine but the challenge is it trigger the alert on AD server as  "user of computer logged on to this computer from the network"  , but script is executing on any server not on AD. Why this is happening I am not able to find out it. Is the AD level security configured or hardening which is creating this problem.

Where I do find the exact cause of this. Can any one help me please. 

I am attaching the script here for the reference.
