A problem was discovered when making an imaging reservation for an AD joined Windows image where there is a logic problem between using the logged in user's account from AD and using the local Administrator account for the reservation. It is no longer necessary to use the Administrator account for imaging reservation. Additionally, any reservation where the user would have rights to select the reserved image as a base image can be captured. In these cases, the Administrator account is not used anyway.
The simplest solution, and one that helps to simplify the code overall, is to just stop using the Administrator account for Windows imaging reservations and simply always use the logged in user's account.
