There doesn't seem to be any resolution to this issue. It's specific to IIS on Windows. The nature of the problem is a 'sharing violation' such that IIS will not allow the deletion of a photo album folder because IIS has a file lock on the folder. I can't even go in through Windows Explorer on the IIS server and delete the album folder manually (while the Web Publishing service is running).
To delete an album folder, the Web Publishing service has to be stopped (no, stopping the individual album website isn't good enough, the entire IIS service needs to be stopped), then I needed to go through windows Explorer on the IIS server and delete the albulm folder manually. Re-start the Web Publishing service and the album folder is now gone from the album software. Totally not the way I want to be deleting albums because it's such a manual process so I guess the end result is that I (and my album users) won't be deleting albums through the album software. Not a show stopper, just more of an annoyance. There must be some way to program the album application to tell IIS not to maintain restrictive locks on these album folders.
Using Sysinternals Filemon, this screen shows the system failure at the file level when trying to delete an album via the album software:
