Here's some powershell script/command to find who is logged in on a RemoteMachine.

Get-WmiObject -computerName ComputerName -class Win32_ComputerSystem -Property UserName | findstr UserName

Finding dependencies for .net assemblies

Have you had .net assembly version mismatch problems?
How do you find which assembly is referencing an older version of some shared assembly?

Here is a powershell script to list out all the dependencies for all the files in given folder (typically bin/debug or bin/release)
Get script here

what it does is really easy and i must give credit to this guy

Powershell Network Scan - Script

Here's the code/script for network scan I was talking about in previous post here

function HandleShare
{
 $share = $args[0];
 write-host ***Scanning Share $share
 #write-host net use X: $share 
 $erroractionpreference = "SilentlyContinue";
 $files = Get-ChildItem -recurse -name $share $fileType 
 $erroractionpreference = "Continue";

 foreach($file in $files)
 {
  if($file.length -gt 0)
  {
   $filepath = $share + "\" + $file;
   write-host $filepath
  }
 }

}

function HandleHost 
{
 $hostname = $args[0];
 $hostname = $hostname.substring(0, $hostname.indexof(" "))
 #write-host "***Scanning Host " + $hostname;

 #List shares.
 $shares = net view $hostname | findstr " Disk" 
 foreach($share in $shares)
 {
  if($share.length -gt 0)
  {
   $tmp = $share.substring(0, $share.indexof("Disk"));
   $tmp = $tmp.Trim();
   $tmp = $hostname + "\" + $tmp;
   HandleShare $tmp;
  }
 }
}

function DisplayUsage
{
 write-host
 write-host -foregroundcolor green "Usage:"
 write-host -foregroundcolor green "       scan.ps1 fileType maxNoOfMachines"
 write-host -foregroundcolor green "       e.g. scan.ps1 *.txt 10"
 write-host
}

function Main
{
 $hostnames = net view | findstr "\\";
 foreach($hostname in $hostnames)
 {
  $maxNoOfMachines = $maxNoOfMachines - 1;
  if($maxNoOfMachines -lt 0)
  {
   exit;
  }

  HandleHost $hostname;
 }
}
