Hi,
Did you resolve this issue ?
I have the same setup and am experiencing the same problem.
I have done all the obvious. Port Forwarding for 80 and 9000.
Configured network settings on the DVR.
When I type the IP of the DVR into my browser I get the KGuard login screen, however I get Invalid Login.
If I go via the Kguard Center and add the DVR, I get the same error messages as you.
One thing that puzzles me - This worked ok until I enabled User1 and set up a password for it.
Then I got annoyed with the box continually asking me to key in a password, so I disabled User1 and reset the
default settings for the 'admin' password.
I have rebooted, restored all of the box to defaults, and it still gives the same messages.
I am figuring something has been affected by the password change ?
If I am getting the Kguard screen loaded from my IE browser, then the issue cannot be network and must be a login one ?
Regards
Nigel
