In addition to removing the "Forgot Password" function, Hikvision has stopped issuing password recovery requests. A request submitted after this report was released received the following response from Hikvision:
The response did not make it clear that the function/support was removed, nor did they recommend downloading the latest release with the "upgraded security structure".

Enterprise level customers would not be using the iVMS4200 platform, it is more realistic to use Hik-Central.
