When you deploy a template, clone an existing virtual machine or when you convert (P2V), you have the opportunity to customize the new guest operation system and it’s done with SysPrep (just for Windows system).
Before you run the Guest Customization wizard you need to set up the SysPrep files on your Virtual Center.
Microsoft includes the SysPrep tool set for each version of operational system, Windows 2000, Windows 2003, XP, versions for 64bits and SysPrep 1.1 from the Microsoft web site.
So you need to download each one of them and extract specific files to a specific directory on Virtual Center, sounds trick right ?!?
So, to help you guys I already downloaded the files, placed them into their correct folders, now, you just need to download it, extract them to C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\sysprep\ on your virtual Center Server.
Here’s a good VMWARE KB about it.
See you next..
