I'm currently working on an desktop tool to automate VPN connections to customers. I'd like to have a good way to know for sure I'm indeed connected to a VPN. I'm currently thinking about using the routing table as it's shown in netstat-rn and comparing it to the IP I should be connected to.
My question is, how would I be able to get these IP's in my C# application, or is there a better way to determine if I'm connected to a VPN.
Thanks in advance!
This is so classic, I spend a couple of hours looking for the solution, and when I ask for help I find it myself.
For those who wonder, this as the solution.
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_IP4RouteTable");
ListViewItem buf;
foreach (ManagementObject queryObj in searcher.Get())
{
string destination = queryObj["Destination"].ToString();
string mask = queryObj["Mask"].ToString();
string metric = queryObj["Metric1"].ToString();
string interfaceIndex = queryObj["InterfaceIndex"].ToString();
string nexthop = queryObj["NextHop"].ToString();
string protocol =queryObj["Protocol"].ToString();
string type = queryObj["Type"].ToString();
string status;
if (queryObj["Status"]!=null)
{
status = queryObj["Status"].ToString();
}
else
{
status = string.Empty;
}
buf = new ListViewItem(new string[] {destination,mask,metric,interfaceIndex,nexthop,protocol,status,typ});
list_route.Items.Add(buf);
}
}
catch (ManagementException ex)
{
MessageBox.Show("An error occurred while querying for WMI data: " + ex.Message);
}
Anyway, thanks everyone who took the time to try and help me!

I am trying to figure out if the Active Directory Domain Services are installed a windows server.
I know they show up in the Server Manager, but can I programmatically get if the role is installed on a server using C# code
If you know the name of the server you want to test and can run the program with domain admin privileges remotely, you can use WMI:
internal static bool IsDomainController(string ServerName)
{
StringBuilder Results = new StringBuilder();
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("\\\\" + ServerName + "\\root\\CIMV2",
"SELECT * FROM Win32_ServerFeature WHERE ID = 10");
foreach (ManagementObject queryObj in searcher.Get())
{
Results.AppendLine(queryObj.GetPropertyValue("ID").ToString());
}
}
catch (ManagementException)
{
//handle exception
}
if (Results.Length > 0)
return true;
else
return false;
}
If you're running that locally on the server, the WMI path changes to:
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_ServerFeature WHERE ID = 10");
See the MSDN reference on Win32_ServerFeature for a full list of roles and their ID numbers.
If your question is to see if a server is a domain controller, you can enumerate the domain controllers in the domain and check the hostname of the server you are sitting on to see if it matches any of them. To get the list of domain controllers:
var domainControllers = new List<string>();
var domain = Domain.GetCurrentDomain();
foreach (var dc in domain.DomainControllers)
{
domainControllers.Add(dc.Name);
}
string whoami = Dns.GetHostname();
Make sure to add requisite error handling (like if you run this on a workgroup computer, it will die).
EDIT:
Alternate ways of detecting DCPROMO (because it's possible to install Domain Services without DCPROMO, and that is a bad thing):
1) Parse out (and check for the existence of) the debug log that is created when DCPROMO does its thing. Should be located at c:\windows\debug\dcpromo.log
2) This DSQUERY command is FAST and will give you all the servers where DCPROMO was ran:
dsquery * "cn=Sites,cn=Configuration,dc=MyDomain,dc=com" -Filter "(cn=NTDS Settings)" -attr distinguishedName whenCreated
Problem is getting that from command line output if you started it using Process. Working on a way to do this and will update once I have it tested, as I haven't done AD filtering in a query for a while.
I have to create an executable which checks if a certain process is running for a certain user (a service account) on a remote machine, the input parameters are 3 strings, machine name, user name and process name.
I have the idea to do this using either System.Diagnostics or WMI, just wanted to double check if anybody has another idea like powershell or even a window functionality which could make the task even easier.
since we want to make sure that process is always running on a dedicated server we will configure a scheduled task to execute a small console application which does this check. Not sure if coding it in C# is the best option or am I ignoring a builtin feature of windows server? Thanks!
I'm pretty sure you can accomplish this with tasklist cmd: tasklist /S \\<server> /V > tasklist.txt. this will give you a file you can grep through.
namespace not referenced
using System.Management;
I have ended up by implementing following solution in C#
this retrieves the username without domain name of the user running processName on machineName
public static string GetProcessOwner()
{
try
{
var resultUserName = string.Empty;
ConnectionOptions opt = new ConnectionOptions();
string path = string.Format(#"\\{0}\root\cimv2", machineName);
ManagementScope scope = new ManagementScope(path, opt);
scope.Connect();
var query = new ObjectQuery(string.Format("Select * From Win32_Process Where Name = '{0}'", processName));
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
var processList = searcher.Get();
foreach (ManagementObject obj in processList)
{
string[] argList = new string[] { string.Empty, string.Empty };
int returnVal = Convert.ToInt32(obj.InvokeMethod("GetOwner", argList));
if (returnVal == 0)
{
// return DOMAIN\user
//return argList[1] + "\\" + argList[0];
resultUserName = argList[0];
}
}
return resultUserName;
}
catch (Exception exc)
{
Debug.WriteLine(exc.Message);
return string.Empty;
}
}
GetOwner can return empty array for remote comp, so it may not work
I'm a c# newby who want to learn more about programming. So I started with a simple tool, wich can set the address of a choosen network adapter to static or dynamic (like the Windows TCP/IP Properties. I set the tool's design exactly like the TCP/IP Properties).
Setting a static IP address to the network adapter works pretty good.
But when I disconnet the Computer form the network and then set the network adapter's IP to dynamic (Obtain an IP address automatically"), it won't set the Windows IP Propertie to dynamic. I'm totaly lost with this problem, I have no idea how to solve it.
I understand that I only get an IP address automatically, when I'm connected to a network (where a router or a DHCP server is enabled).
But when I disconnect the computer form the network, an I set the IP Properties to dynamic with the the Windows TCP/IP Properties, it works well. What is worng in my code?
Thanks a lot for your help!
Below the code I'm using:
public void setDHCPMode()
{
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if (!(bool)mo["ipEnabled"])
continue;
try
{
string desc = (string)(mo["Description"]);
if (desc == NICcomboBox.Text)
{
ManagementBaseObject newDNS = mo.GetMethodParameters("SetDNSServerSearchOrder");
newDNS["DNSServerSearchOrder"] = null;
ManagementBaseObject enableDHCP = mo.InvokeMethod("EnableDHCP", null, null);
ManagementBaseObject setDNS = mo.InvokeMethod("SetDNSServerSearchOrder", newDNS, null);
}
toolStripStatusLabel1.Text = "DHCP set";
}
catch (Exception ex)
{
MessageBox.Show("Unable to set DHCP : " + ex.Message);
}
}
}
I found the problem. It looks like the WMI dosn't work correctly. It's impossible to set the TCP/IP Properties to DHCP, while the cable is unplugged for the specific NIC.
I solved it, through setting DHCP mode in the regestry. Now it works perfectly.
I need to check a group of servers to see whether the anti virus is up-to-date and running. Tricky thing is that they are spread over Windows 2003 and 2008 servers and I need to be able to check them all.
Is there any way of doing this with C# or VB.NET?
I have briefly looked around using WMI, but it appears on 2008/win7 computers Microsoft has changed what information they give back to you.
In summary, I need the following:
AV name
AV version
AV Up-to-Date
AV Enabled/Running
Can anyone help?
Sample can be found here using WMI as you mentioned. The poster states this is being done on a Win 7 machine; so the code below should get you started...
ConnectionOptions _connectionOptions = new ConnectionOptions();
//Not required while checking it in local machine.
//For remote machines you need to provide the credentials
//options.Username = "";
//options.Password = "";
_connectionOptions.EnablePrivileges = true;
_connectionOptions.Impersonation = ImpersonationLevel.Impersonate;
//Connecting to SecurityCenter2 node for querying security details
ManagementScope _managementScope = new ManagementScope(string.Format("\\\\{0}\\root\\SecurityCenter2", ipAddress), _connectionOptions);
_managementScope.Connect();
//Querying
ObjectQuery _objectQuery = new ObjectQuery("SELECT * FROM AntivirusProduct");
ManagementObjectSearcher _managementObjectSearcher =
new ManagementObjectSearcher(_managementScope, _objectQuery);
ManagementObjectCollection _managementObjectCollection = _managementObjectSearcher.Get();
if (_managementObjectCollection.Count > 0)
{
foreach (ManagementObject item in _managementObjectCollection)
{
Console.WriteLine(item["displayName"]);
//For Kaspersky AntiVirus, I am getting a null reference here.
//Console.WriteLine(item["productUptoDate"]);
//If the value of ProductState is 266240 or 262144, its an updated one.
Console.WriteLine(item["productState"]);
}
}
Depending on how your environment is setup you may need to specify your security and permissions. You should also note that some antivirus products (like McAfee) do not make data available through WMI.
You can query the Antivirus information from WMI using this snippet:
string computer = Environment.MachineName;
string wmipath = #"\\" + computer + #"\root\SecurityCenter";
string query = #"SELECT * FROM AntivirusProduct";
ManagementObjectSearcher searcher = new ManagementObjectSearcher(wmipath, query);
ManagementObjectCollection results = searcher.Get();
foreach (ManagementObject result in results)
{
// do something with `result[value]`);
}
Is there anyway using WMI/.Net to grab monitor information such as Manufacturer, Serial Number, Monitor Size etc.?
Using a script is an option as well, or can I query the registry directly to get this information?
SELECT * FROM Win32_DesktopMonitor doesn't really return any useful information for me in this case.
Hey, I use this tool for a lot of my WMI work, especially when prototyping and creating POCs....
Microsoft WMI Code Generator
This tool is great for creating quick console app code for any wmi query or method invocation in both C# and VB.NET
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_DesktopMonitor");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("-----------------------------------");
Console.WriteLine("Win32_DesktopMonitor instance");
Console.WriteLine("-----------------------------------");
Console.WriteLine("Description: {0}", queryObj["Description"]);
}
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
The code above will get you the make and model of the monitor.
You may want to try this
https://raw.githubusercontent.com/MaxAnderson95/Get-Monitor-Information/master/Get-Monitor.ps1
Cheers
That select query should give you what you want. Here is the documentation which contains the details of the query.
Then you could do something like this:
public void GetMonitorDetails()
{
using(ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DesktopMonitor")
{
foreach(ManagementObject currentObj in searcher.Get())
{
String name = currentObj("Name").ToString();
String device_id = currentObj("DeviceID").ToString();
// ...
}
}
}
This post, combined with the answer below about the WMI management tool had my answer. Here is the code that returns your monitor resolutions.
try {
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\WMI",
"SELECT * FROM WmiMonitorBasicDisplayParams");
foreach (ManagementObject queryObj in searcher.Get()) {
Debug.WriteLine("-----------------------------------");
Debug.WriteLine("WmiMonitorBasicDisplayParams instance");
Debug.WriteLine("-----------------------------------");
Debug.WriteLine("Description: {0}", queryObj["SupportedDisplayFeatures"]);
}
} catch (ManagementException e) {
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
In my case, I'm still stuck, because it is returning the "scaled down" resolution of each monitor. One of mine is a 4K display, being reported as 2560x1440.
