The DVR DVR password is forgotten and locked with too many input errors. How do I reset my password?

It mainly depends on where your combination lock is.

1.If it's boot on, motherboard password, do you just open the case and see the battery on the motherboard? Take it out and put it back again.

2.If it's a user password that you create by yourself, it's easy, change the username to administrator, don't use the password, and you can enter it if you are sure.

3.You can also turn on the computer and press F8, enter the security mode, enter the administrator user (generally there is no lock password), find the user you want to enter (Control Panel - Users), and delete the password.

Added: If you accidentally forget your password and cannot log in to Windows2000, you only need to start the computer with the startup disk or boot into another operating system (if the computer has win98 and win2000 dual systems), find the folder "X: documents and settings administrator" (X is the drive letter of the disk where Windows2000 is located), and add this file.

Delete the "cookies" folder and restart the computer, you can quickly log in to Windows 2000 with an empty password. For security reasons, users can reset their passwords for each user.

In fact, if we accidentally forget the superuser password and cannot log in to Windows 2000, we can recover the password without reinstalling the system. The principle is to delete the SAM file where Windows 2000 stores the user's password, so that the password is empty. If Windows 2000 uses FAT32 partitioning, then just boot the system directly with the boot disk and enter the DOS state.

Restart the computer by typing :delc: winnt system32 config sam in the DOS prompt, and when you enter the Windows 2000 login screen again, the administrator's password will be empty.

If Windows 2000 is using NTFS partition, you can use a tool such as NTFSPRO to load the NT partition in DOS mode, and then delete the C: Winnt System32 Config SAM

Unplug the power cord and detach the button cell battery inside.

Remove the com battery and factory it or unplug the jumper.

I didn't see it. Reset empty.

Is this password something you set before?

You can try a simple 123, 123456, uh, but you can see if you have tried the password first.

Tried it but didn't respond.

It's just that you don't respond when you enter the password, right? Then you can see if it is the cause of the machine itself.
