4 times in the past 3 weeks my DS-2DE7230IW would lock and then display "incorrect username or password" for no apparent reason. The first 3 times happened during business hours, so I was able to send in the XML file and get the password reset (the default password would not work.) I brought this to the attention of support and told me they never heard of the problem and I need to send it back to the seller for an exchange...I said for a password reset?!?! This is got to be a firmware issue, but they ignored me.
Anyway, it happened again tonight AFTER BUSINESS HOURS and I was in a pinch until I came across this reset tool....thank you!!!
I was about to give up using these cameras because of this issue and their reset method...which I understand to some extent but don't know why it is only available during business hours.
