To start off, this is an application I use almost daily. It's very simply titled Remote HealthCheck. As implied by the name, it remotely checks the "health" of computers in your environment. This uses WMI calls, Active Directory searches, UNC paths, etc to gather information about a computer and it's state. We will also create our own dll for storing commonly used functions. Of course, you'll need to modify based on your environment. When done, you'll also be able to search Active Directory and query an entire OU.

Part 1: Create your functions library
The reason I created a functions library is because most of these functions I use in many of my projects, so it's nice to just be able to reference this library and call the functions, without having to rewrite them.
Step 1: Create a new library project.
Mine is named THRFunctions... my company and Functions... unoriginal I know, but simple and to the point.
Step 2: Add your references
Add a reference to System.DirectoryServices. This allows us to work with Active Directory. Also, a reference to System.Management (can't remember if this is automatic or not.. but whatever)
Step 3: Code your library
Alright, here's the fun part. We need to create our functions that will be used for our projects.
When you copy / paste this into your IDE, you will find some errors. I placed these there on purpose because these are things YOU need to fill in based on your environment.

Ok, after you modify all of that, you can build it, and grab the dll.
Part 2: Writing the application
Now here's where we get down to the area where we can tell the application what to do.
Step 1: Create a new Windows Forms Project
Mine is simply name Remote HealthCheck, and is using .NET 3.5 framework.
Step 2: Add References
Add these references:
Microsoft.Office.Interop.Excel
System.Data.DataSetExtensions
System.DirectoryServices
System.Management
System.ServiceProcess
THRFunctions (whatever you named yours, reference it)
Step 3: Create File Structure
We have multiple forms, and a class that need to be added.
Root [INDENT]AddComputers[/INDENT] [INDENT][INDENT]frmAdd.cs - Windows Form[/INDENT][/INDENT] [INDENT][INDENT]frmADSearch.cs - Windows Form[/INDENT][/INDENT] [INDENT]clsGlobal.cs - Class[/INDENT] [INDENT]frmMain.cs - rename Form1.cs[/INDENT]
Leave everything else as is.
Step 4: Setup the clsGlobal class
Very simple:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Remote_HealthCheck
{
class clsGlobal
{
public static String g_targets;
public static String g_sString;
public static String g_rString;
}
}Step 5: Design the frmAdd form
Open frmAdd [Design]
Change the FormBorderStyle to FixedToolWindow
Size = 319,336
SizeGripStyle = Hide
StartPosition = CenterParent
Text = Add Computers
TextBox: txtPCs
Location = 11,7
Multiline = True
ScrollBars = Vertical
Size = 291, 268
Button: btnADSearch
Location = 11,282
Size = 129,23
Text = Active Directory Search
Double click it to create a function for it, we'll come back to that later
Button: btnFormat
Location: 146,282
Size = 75,23
Text = Format
Double Click, come back to it later
Button: btnDone
Location = 227,282
Size = 75,23
Text = Done
Double Click, come back to it later
When finished, it should look like this:
Now for the code to this form:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Remote_HealthCheck.AddComputers
{
public partial class frmAdd : Form
{
public frmAdd()
{
InitializeComponent();
}
private void btnFormat_Click(object sender, EventArgs e)
{
string tempPcs = "";
int i = 0;
foreach (string computer in txtPCs.Text.Split(Environment.NewLine.ToCharArray()))
{
i++;
if (i == 1)
tempPcs = computer.Trim();
else
{
if (computer.Length > 2)
tempPcs += Environment.NewLine + computer.Trim();
}
}
txtPCs.Text = tempPcs;
}
private void btnDone_Click(object sender, EventArgs e)
{
clsGlobal.g_targets = txtPCs.Text;
this.Close();
}
private void btnADSearch_Click(object sender, EventArgs e)
{
frmADSearch objfrmADSearch = new frmADSearch();
objfrmADSearch.ShowDialog();
txtPCs.Text = clsGlobal.g_targets;
}
}
}
Step 6: Design the frmADSearch form
Form settings:
FormBorderStyle = FixedToolWindow
ShowIcon = False
Size = 382,105
SizeGripStyle = Hide
StartPosition = CenterParent
Text = Active Directory Search
TabControl tabControl1
Dock = Fill
TabPages = Collection (Open)
TabPages:
0 - tabName
Text = Name Search
1 - tabOU
Text = OU Search
Go to tabName
TextBox txtName:
Location = 6,6
Size = 196, 20
ComboBox cmbNameArg
DropDownStyle = DropDownList
Location = 217,6
Size = 121,21
Items = Collection:
Starts with Ends with Contains
Button btnNameSearch
Location = 8,32
Size = 75,23
Text = Find
Double Click, we can come back to it later.
tabOU:
ComboBox cmdOUList
Location = 8,6
Size = 236,21 (you can lengthen if you wish)
Button btnOUSearch:
Location = 8,33
Size = 75,23
Text = Search
Double Click
Code for this form:

You'll notice there are some sections you may need to modify, such as public int HasAdmin(string target)
Change the memberEnrty.Name 's to match whatever the local admins for your computers should be.
Also, this section:
public string LastLoggedIn(string target)
{
var conn =
new SqlConnection(@"Data Source=FTWSCCMSQL01\INSTANCE1;Initial Catalog=SMS_TH1;Integrated Security=True");
conn.Open();
string strSqlCommand = @"SELECT User_Name0
FROM v_R_System
WHERE (Name0 = '" + target + @"')";
var command = new SqlCommand(strSqlCommand, conn);
var commreturn = command.ExecuteScalar();
var returnVal = commreturn != DBNull.Value && commreturn != null ? commreturn : "none";
conn.Close();
return returnVal.ToString();
}Will need to be either reconfigured (if you have SCCM), or you can simply do a registry query against the target computer for this information:public string LastLoggedIn(string target)
{
RegistryKey myKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, target);
myKey = myKey.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon");
try{UserName = myKey.GetValue("DefaultUserName").ToString();}
catch { UserName = ""}
return UserName;
}Now, we have also have some Resources:
Open your project properties:
Resources:
strProgressStatic = Progress: 0 / (I may not even have this in my code anymore.. if not, sorry)
