Hi Roger,
The DefaultMaster parameter of any subsite contains the path to the default master skin starting from the installation's root directory (eg, /web/servername). So "/www/templates/default/index" would be a valid entry if your master template files were located at "/web/servername/www/templates/default/index.(tcl/adp)".
Don't know if that means the problem was fixed, but I assume so.
