USERPROFILE

When you run the set command you see a variable USERPROFILE set - does anyone know why this variable would be returning a different value based on running from Windows Server via dos prompt and LID?

From dos on server:
USERPROFILE=C:\Users\cpaine

From LID:
USERPROFILE=C:\Windows\system32\config\systemprofile

And does anyone know how to force this value to be:
USERPROFILE=C:\Users\Default

and make it stay?
