How to obtain VMware server?
Before you begin installing VMware Server, you first need to obtain it. Fortunately, for all of us, VMware server is available for FREE. However, even though it is free, you must register to obtain a serial number to use it. To register, go to the Download VMware Server website and don't forget to Register. By registering, you will receive a VMWare Server serial number, like this:

Once you have the serial number, copy and paste it to notepad so you can use it later. Now click the Download Now link on that webpage. You will have to click Yes to accept the end user license agreement. On the next screen, click that you want to download the Binary.exe file, like this:

Click that you want to Run the executable when the download is completed. When the download is completed, click Run again and the executable will start the VMware Installation Wizard.
How to obtain VMware server
Inside the VMware installation wizard, click Next to get started. Accept the license agreement and click Next. Take the default of a complete installation by clicking Next. If you are running Windows XP as your host operating system, you may get a message like this:

This is because we are using Windows XP as the host operating system and VMware doesn’t recommend running VMware server on a Windows XP desktop (nor do they offer support if you are doing it). However, I haven’t talked to anyone who has had problems doing this, as long as you are only using VMWare Server under Windows XP for app testing & development. Of course, you would not want to run production servers using Windows XP as the host OS. So just click OK on this error and proceed with the installation.
Now, take the default destination folder and click Next.
If you have autorun enabled on your CDROM drives, you will now see this window:

Because autorun can cause problems when a CDROM with an autorun file is inserted, I recommend taking the default and disabling autorun. Click Next.
Finally, click Install to begin the installation. The setup will proceed and VMware server will be installed.
As I did, you too may get the following error in the install process:

For now, click OK on this error. For information on how to handle this error, see the separate article on Starting the VMWare Web Service. This error won’t prevent the installation from being successful.
After the installation is complete, you will be asked to provide customer information. Enter your User Name in the box provided. Then go back can copy your serial number from notepad. Now paste that Serial Number in the proper box on the VMware customer information screen. Here is an example:

Click Enter, and you will see that the Installation Wizard completed and you must restart your computer.

Once your computer restarts, the installation is completed.
What to look for after the installation
After the install is done, what do you do? Well, the first thing you may notice is a VMware Server Console button down on the quick launch section of your taskbar. It looks like this:

You will also have an icon on your desktop for the VMware Server Console. As with most programs, you will have some new icons in your Start menu. Specifically, there are two new icons under Start àVMware à VMware Server. They are VMware Server Console and Manage Virtual Networks.

If you click on the VMware Server Console button on your taskbar, the console will appear, like this:

Click OK to connect to your local host VMware system (this console can be used to connect to remote VMware servers as well). The first thing you would normally want to do on VMware server is to create a new virtual machine. To begin that process, click on the New Virtual Machine button, like this:

I won’t go into how to create a new virtual machine but the process is pretty self-explanatory.
An alternative to creating a new virtual machine is to download a pre-built virtual machine. This can be done through the VMware Virtual Appliance Directory.
Summary
VMware Server is an amazing program and it is even better now that it is free. VMware Server download and installation isn’t difficult but it is important to know the proper steps so that you aren’t just taking your best guess. What is even better is knowing the “gotchas” before they “get you”. This prevents you from spending a lot of time trying to troubleshoot some weird installation error.
