Here is the VMware View video that we mentioned in an earlier post today.
This video tutorial provides a demonstration of creating a QuickPrep user account for VMware View Composer operations.
View Composer requires QuickPrep to join linked-clone desktops to your Active Directory domain. To ensure security, create a separate user account to use with View Composer. You can give the account the minimum privileges that it needs to create and remove computer objects in a specified Active Directory container. The View Composer account does not require domain administrator privileges.
For additional instructions, see VMware Knowledge Base article Creating a QuickPrep user account for VMware View Composer operations (1025834).
