Web Analytics Shows 0 Unique Visitors, but Reporting DB Shows Different

Hi all,

I am having another Web Analytics issue with SP2010. This time one of my clients is showing 0 unique visitors. When checking the Reporting Database though I am seeing many visitors (so therefore there must be unique ones) in the WAVisitorAggregationByDate table on the dates where 0 is shown in the site. "Number of Page Views" and "Number of Referrers" are both reflecting data as expected. Only "Number of Daily Unique Visitors" is not. Any ideas on why this is not reflecting the correct numbers?

Any help would be greatly appreciated.

Thanks,

J.
