Clayton:
My experienece with this has been that MS changed the way this is done in Office 2003. You need the Resource Kit for Office 2003 Toolbox Found here:
http://www.microsoft.com/office/orkarchive/2003ddl.htm which provides another method, using the Custom Maintenance Wizard (MaintWiz.exe), then you export a PRF file for your current Outlook properties, and then you use a pointer to the CMW file (Custom Maintenance wizard file) that is generated at the end. I found for 2003 that the profgen, modprof are not supported. But then again, I may need to be slapped as well. Just my thoughts, hope it helps.
