I have just setup ATA on a 5 node hyper-v cluster...

The DC and ATA VMs are spread across nodes.

I have configured all the mirroring etc... however when I open ATA Center and search for user, the user appears but there is no activity for logon etc...

Hi, please see the discussion regarding Hyper-V and clusters here and see if this matches your current scenario,

Thanks,

The ATA Team.
