    Anthony Mueller did you get an answer on this? I'm having the same issue recently within our environment with 1 IP address getting 300K+ request from Alert Logic Appliance and it seem to be during the default discovery scan timeframe.

    Apologies I never responded back on this back when we figured it out.

    So basically what was learned is AlertLogic appliances do run scheduled brute force attempts on a list of generic accounts which includes 'Administrator' to test security etc. After a lot of discussions, several things happened. One, I believe we had the IP of the appliance whitelisted so it wouldn't keep reporting itself. Then two, per MS best practice we created a new administrator account with another name and then disabled the default 'Administrator' account on the server.
