WMI SELECT * FROM DhcpServerv4Scope Returns empty. RRS feed

  • Question

  • I am trying to get a list of DHCP Scopes from Windows Server 2019 (Essentials) by running  

    this WMI Query:  SELECT * FROM DhcpServerv4Scope  but it returns empty. No errors, just empty.

    DHCP Server has lots of Scopes so I really expect some data in return.

    Using Name space: ROOT\Microsoft\Windows\DHCP

    Any help is appreciated.

  • Get a specified instance of DhcpServerv4Scope by a key, get a default unnamed instance (singleton) of the class or list instances of the class by <g class="gr_ gr_3 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="3" id="3">wmi</g> query using this c# sample code.

    	//Project -> Add reference -> System.Management
    	//using System.Management;
    	//create a management scope object
    	ManagementScope scope = new ManagementScope("\\\\.\\ROOT\\Microsoft\\Windows\\DHCP");
    	//create object query
    	ObjectQuery query = new ObjectQuery("SELECT * FROM DhcpServerv4Scope Where PropertyName=\"SomeText\"");
    	//create object searcher
    	ManagementObjectSearcher searcher =
    	                        new ManagementObjectSearcher(scope, query);
    	//get a collection of WMI objects
    	ManagementObjectCollection queryCollection = searcher.Get();
    	//enumerate the collection.
    	foreach (ManagementObject m in queryCollection) 
    	  // access properties of the WMI object
    	  Console.WriteLine("ActivatePolicies : {0}", m["ActivatePolicies"]);

  • Well.. 

    You suggesting to use  "SELECT * FROM DhcpServerv4Scope" statement where my original question

    stating that it does not return any data. Is there a reading disconnect?

  • Try with powershell query "Get-DhcpServerv4Scope -ComputerName ""
    Thursday, January 3, 2019 7:16 AM
  • Power Shell Query works fine: 

    PS C:\Users\Administrator> Get-DhcpServerv4Scope

    ScopeId         SubnetMask      Name           State    StartRange      EndRange        LeaseDuration
    -------         ----------      ----           -----    ----------      --------        -------------   Saratov        Active     8.00:00:00   Vilnus         Active      8.00:00:00

    But direct WMI Query returns Empty.  I am using "WMI Explorer" application to browse classes.

  • Try with the below query 

    Get-WmiObject -Namespace ROOT\Microsoft\Windows\DHCP -List

    Get-WmiObject -Namespace ROOT\Microsoft\Windows\DHCP -List | Where-Object Name -eq 'PS_DhcpServerv4ScopeStatistics'
