To eliminate any uncertainty as to how the connection is made, at a command prompt you can just enter "net use" and it will report network shares that are attached.
Mike, let me offer a couple of pieces of advice...
Until the problem that's causing this reimporting is resolved, you might consider if you actually need auto import. Unless you're constantly updating your files using other programs, you probably don't need it and can just turn it off.
Secondly, I would strongly advise you to reconfigure your Recent Albums view so it does not depend on Date Imported. That's just a bad practice. There may well arise legitimate reasons why you may actually need to reimport files at some point, and breaking the Recent Albums view is a drag. If you create a custom date field, "Date Acquired" you can base your Recent Albums view on that. It is no additional overhead as you can have MC automatically fill out the field on first import. But as a separate, custom field, it is not subject to modification the next time you import the file. Just ensure the field is saved in file tags. It's a much better solution and will keep your Recent Albums view from ever getting wrecked.
