I have a DVR that has been connected to the network. I am able to connect to the login screen with Internet Explorer, however when I try to login as admin it tells me "login failed". I have created a new user and gave the user full permissions, however I get the same error message. Do you know what could be causing the problem?

I have a DVR that was made in 2010. The DVR beeps, then restarts randomly and intermittently by itself. I have checked and it is not that my harddrive is full. Once it restarts I cannot use the front panel or remote to control it. Sometimes it works, where I can control it and the boot-up has no problems. What could be causing this issue?
