Thank you both again - it does make sense and just in case, I added the same mapping to the server and chksys reports 0 errors and 0 warnings.

I still have this other user, who is a "Power User" on the server and looks like an "Administrator" locally, same as my login. However the Adagio workstation setup reports insufficient rights locally to install. I am checking further into setting up users in this "domain" environment Windows 2003 Server uses.
