I am having some issue deploying a VM from template with guest customization. I have not been able to find any answers on the web. Here is my setup:

vSphere 5.1.0 Build 1064983

  1. Create a VM (WIN2K8R2) based on Windows Server 2008 R2 with Administrator password as P@ssw0rd
  2. Install VMware Tools
  3. Activate Windows
  4. Shutdown VM (WIN2K8R2)
  5. Clone VM (WIN2K8R2) to a template (WIN2K8R2T1)
  6. Deploy a VM (WIN2K8R2T1S1) from template (WIN2K8R2T1) with Guest Customization Spec
  7. VM (WIN2K8R2T1S1) successfully created from template (WIN2K8R2T1)

  • Issue is, if i don't set "Automatically Logon as Administrator" in the Guest Customization Spec, i cannot logon to windows.
  • If I set "Automatically Logon as Administrator", the VM automatically logon, but if i log-off, i cannot logon
  • If I set "Automatically Logon as Administrator", the VM somehow removes the "Administrator" password. And if I go to "Edit Local Users", i get option "Set New Password" for the Administrator user. Once I set a new password, then i can use the new password to logon.
  • I also see that the Windows is no longer activated.
  • If i specify domain credentials in the customization spec for the VM to be joined to a domain, it does not join it.
  • it looks like the guest customization is not really working?

Any idea what is going on here? I have been able to reproduce this with Windows Server 2008 R2 and Windows Server 2012.

Found this to be a bug when using the vSphere Web Client. When using the vSphere Client for Windows, customization works fine.
