The document describes a PowerShell script that maps and unmaps network drives on remote machines to test session validation. It provides the source code, runs the code twice with different sleep times, and checks the job status and NAS session statistics after running the code. The script maps drives, sleeps, then unmaps them on multiple remote machines using jobs and verifies the jobs complete as expected while monitoring NAS session activity.
