Background
You want to create Project Server accounts on multiple worstations.
Resolution
When you create a Project Server account on your local workstation, the system adds the following reistry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\12\MS Project\Profiles\<ProjectServerAccountName>
You can export this registry key and then distribute it through group policy or SMS.
Note: For versions prior to 2007, the reigstry key varies where 12 = Project 2007, 11 = Project 2003, and 10 = Project 2002
