VMware ESXi: Error while cloning a Disk to 2gbsparse format


since ESXi 5.1 it is no more possible to create or clone a disk by using the 2gbsparse disk format. Because it is not supported as a VMFS vitual disk format. This disk format is only part of the Desktop Products of VMware, like VMware Workstation or VMware Player.

Creating  a XML File, create a document root, create subelements, add and set attributes, save the file

# Create a new XML File with config root node
[System.XML.XMLDocument]$oXMLDocument=New-Object System.XML.XMLDocument
# New Node
# Append as child to an existing node
# Add a Attribute
$oXMLRoot.SetAttribute("description","Config file for testing")
$oXMLSystem.SetAttribute("description","Document Management")
# Save File

Loading an existing XML File, read an element, do some XPATH queries

Windows: Create a new local User Account and add them to a local group by using .NET and C#


a short post. It describes how to create a new local Windows User account and add them to an existing local user group.

First of all, include the following references in your project:

using System.DirectoryServices;
using System.Runtime.InteropServices;

Create a new User with local administrator rights.

// define Username and Password
const string USER_NAME = "NewAdmin";
char[] aPWchars = { 'P', 'a', 's', 's' , 'w', 'o', 'r', 'd'};
System.Security.SecureString oPW = new System.Security.SecureString();
foreach (char cChr in aPWchars) {
// Get Computerobject via ADSI
DirectoryEntry oComputer = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");
// New User
DirectoryEntry oNewUser = oComputer.Children.Add(USER_NAME, "user");
// define Pointer to a string
IntPtr pString = IntPtr.Zero;
// Pointer to password
pString = Marshal.SecureStringToGlobalAllocUnicode(oPW);
// Set password
oNewUser.Invoke("SetPassword", new object[] { Marshal.PtrToStringUni(pString) });
// Add a description
oNewUser.Invoke("Put", new object[] { "Description", "New Administrator" });
// Save changes
// Cleanup and free Password pointer
// Get Group
DirectoryEntry oGroup = oComputer.Children.Find("Administrators", "group");
// And add the recently created user
oGroup.Invoke("Add", new object[] { oNewUser.Path.ToString() });
