We recently upgraded our domain controllers to Windows Server 2008 R2 (Still at functional level 2003).

I went to make a change to one of our login scripts in the SYSVOL\{domain}\scripts\ directory, despite the account I was logged in with having Enterprise Administrator and Domain Administrator permissions it will not let me edit the scripts or add new ones.

I've tried googling around to see if I can find any information but so far I'm turning up dry. Does anyone have any idea how I could fix this?
