I'm not sure what is causing the "Explorer View" in the document libraries to fail. Is there a service that this is attached to? I tried all the administrator accounts both on my DC (virtual machine 1) and the SharePoint v3 install (virtual machine 2). I'm getting so flustered with all the authentication problems with v3 that I'm ready to give up again for the 100th time.
