How to Change SID and Hostname of Virtual machine


Hello and welcome.
I m writing this post simply for the ones who are involved with virtualisation softwares like Vmware, Virtual Box, Virtual PC, etc. Most of the time we need more than one machine in order to make a network. We can achieve this by two methods :
  1. Make two seperate machines and install the operating system, softwares , etc seperatelt and waste a lot of time.
  2. Obviously you are not so stupid to waste your time, so why not make a machine, copy its hard disk in other folder and use it so many times, actually infinite times.
But here a porblem comes, when we connect such copied or cloned machines, You can not connect them in same network , as their SID ( Security Identity) and HOSTNAMES are same. And yes, this is a big problem.

Solution is, we can change the "hostname" very easily from the properties of "my computer" or by command in Lunix. But SID can not be changed this way.

For accomplishing this, i.e. to connect the machines in samew nwtrok, we need to use a software "NEWSID".It is a simple utility exists that enables you to quickly change the SID and the computer name of a cloned virtual machine.
NewSID v4.10 and is available for download free of charge.

If it comes in zipped form , Unzip it application, start it and agree with the licence terms. You will see Welcome screen which tells you what NewSID is and tells you to backup your system before using it.
Dont forget to take backup if you are going on your important machine.

Start Newsid,and at the first screen Click on Next. Now we have a window where we have to choose new SID. Here you have three ways:


  1.  Random Sid (wud calculate some random Sid with mathematical operations.
  2. Copy SID from some oether computer, and here it woud ask you for the location of that second computer.
  3. Or simply, you can give a SID of ur wish as well.
I wud however prefer you to go with Random one as it would save your time.

Next you would be asked for the Hostname. If you cant to change , then specify the new one. Otherwise simply leave it as it is.


By clicking Next you’ll see confirmation window, where you can choose to restart or not to restart computer after applying new SID.

Click on Next and that’s it. Wait for few minutes, and your PC will have new SID and name.

And you are done. Congrats. :) , Lol.

I guess this was useful to to newbies. Any query or suggesstion, drop it as comment.
