That prompts to repeat the previous question from Corinna: are you by chance
remote from your DC? (VPN connection?)

83 vs. 87, still not the right number.

> Not really sure how many groups I'm a member of (in another tool), but seems about right.

Anyway, how was the results after these manipulations?
