I'm somewhat a newbie to this. Anyhow, bought a H.264 DVR on ebay last year. Had it properly set up for remote internet access via Dvrocx.ocx ActiveX software. It worked fine until recently, when all of the sudden, I couldn't log in remotely anymore. When I tried to log in with password, it will say "Login failed!". I had the DVR restored to it's original settings, and started again. When I'm connected with the router that is also connected to the DVR, I can access to my DVR through both LAN and Internet by typing the IP 192.168.X.X:XXXX. One strange thing I noticed, when I tried to change the settings, often a message will pop up saying "Other user configuring..." And it wouldn't let me do any modifications, and sometimes, after couple of tries, the message will disappear, and I can modify again. What does this mean? Does it mean I got another person that is controlling all the settings? But I'm already logged in as the admin. And there is only 1 admin password in the system. Anyone would know what this message means? More problems also found after I tried to log in remotely. I setup my hostname with a Dyndns account. Once entered the address, through dvrocx, I can get into the web application manager log in page, which requires me to log in. But when I enter the same password as before, it would say "login failed!" Why is that using the router conncted to DVR, I could log in with ip address, but with the same password, it would not let me log in through a host address? I'm currently using either Vista and IE8 or Windows 7 and IE9, not sure if that had any effects on anything at all. I tried with both computers, it ended with the same results. Either logged in with ip, but had a strange "Other user configuring..." message or unable to log in remotely using the ddns. Any help here is greatly appreciated. Thx!!!

Thanks for the reply. Yes, after seen your post, I went back into web access through local connection, without also sign into the DVR box, the "Other user configuring..." message did disappear. But, any kind of suggestions on why I'm not able to log in through internet connection? It should be the same password and port I used to log in through LAN. Thx!
