None of the information is correct most likely the licensing module has been removed from Windows 2008 server because it was never inforced and information was not correct in the module.
You should always have paperwork stating how many CALs you actually have since MS will not go by what you have in a licensing module. There is no way to prove or show how many CALs you have unless you have paperwork sorry.
No once EE can give you an answer on how many CALs you should have or purchase you should call MS or a MS approved licensor to speak with on how many CALs are required since MS is the only company or person that can tell you what you actually need since they are the ones providing the licenses.
