Multi-domain usage under Leopard

I'm stuck. I've successfully setup a single group in the wiki under 10.5.0 (and now 10.5.1), but when I try to add a second group wiki I'm getting a "404: No group with that name (prepubgroup) hosted on this server" Now I've got prepubgroup located in about every place that I can think of (obviously not the right spot though). I've got it setup as a domain name and as a Group Name in the Workgroup Manager. Now the odd thing is if I select the prepubgroup under "Enable the following services for this group" (and check the subsequent boxes under that), hit save and then look at the existing (and working) group - the selection for "Enable the following services for this group" has gone to (None). I suspect that it has something to do with the configuration of the Domains under the Sites. I'm more than happy to look around at some documentation on this. If someone could point me in the right direction, I greatly would appreciate it. Thanks, Brian Garrett bgarrett@denvernewspaperagency.com
