"changed the password on the vms"
Does he mean he changed it in the web interface of an NVR?
If so, it's possible that the software rapid-fire tried the wrong password to connect to that NVR and the NVR auto-locked the account. If you go into PSS and take the device offline, then change the password in the NVR, then enter the new password and take the device back online, it should avoid that.
That's actually a good example of the annoyances of these intrusion detection features. I had the same thing happen between Exacq and a Dahua camera.

Sounds like he changed the local password for SmartPSS, not his NVR/DVR. This would explain his inability to connect remotely to the device.

This is a screenshot of SmartPSS (on Mac OS X) showing the account locked problem.SmartPSS reports the DVR to be offline because the account is locked.
In this instance, a child had been playing with a computer which accessed the DVR. Presumably the child tried entering the account password too many times so the DVR automatically locked the account. There's nothing in the manual about how to solve this so I expect I'll have to obtain help from Dahua support.

The DVR automatically restarted last night as it was scheduled to do. The problem remained today. I will ask the customer to try powering it down fully and then start it up again and see if that makes any difference. Thanks for the tip!

You can also use the local login account 888888 (default password 888888) to unlock the DVR. The 8 account only works from a mouse and monitor connected to the DVR, it can't be used to access the webpage or as a PSS login.
