Hi Randy,
>I'm trying to figure out what resource Word is trying to access that this user doesn't have permissions for.
I'd use FILEMON and REGMON from htttp://www.sysinternals.com to monitor what happens while the CREATEOBJECT() line executes.
Since you can start Word interactively, I'd assume that there's something in the profile that Word cannot access, maybe drive mappings... Can you logon as a different user on the server, and drop all drive mappings. Then launch Word using the "Run As..." option.
