    Hey all,

    Suddenly last week, my persistent desktops stopped finishing the customization. I get an error in vSphere:

    Event Type Description:


    The customization component failed to set the required parameters inside the guest operating system


    Possible Causes:


    On Windows, the user account under which the customization code runs has no read/write permissions for the registry keys used by the customization code. Customization code is usually run under the 'Local System' account but you can change this by selecting a different account for VMware Tools Service execution. Action: Determine which user account is selected for VMware Tools Service execution and confirm that this account has read/write permissions on registry keys used by the customization code

    The error points me to the guest customization log. I see the following:

    I use a customization profile which I believe is used to configure sysprep during the system's first initialization. I validated the passwords used are correct. I also found another post mentioning template name length - this template name is less than 15 characters. I have even gone so far as to uninstall our AV and completely rebuild the template from scratch. 

    Has anyone else encountered this problem? Is there a way I can see which account VMware Tools is using (I do not use any custom configuration for that process that I am aware of)? What files, folders, and registry keys does VMware Tools need to perform the customization function?

    Thank you for your time.
