If you have forgotten your admin password on a Samsung Security DVR, most experts would suggest that you have to contact Samsung and/or send it back to Samsung to have the administrator password reset. While this is true in some cases, it is not always necessary.
Many Samsung Security DVRs have a built-in reset that will allow you to wipe the settings of the device and reset the configuration, including the administrator password. Note that if you perform one of these resets, all settings will be erased and you will have to setup the DVR again. So you should only do this as a last resort - but to reset an admin password, the last resort is the only option.
Reset Procedures for Samsung Security DVRs
There is more than one reset procedure for Samsung Security DVRs, depending on the series and model. But in total, this only amounts to a handful. Since one reset can apply to several different models, I'll provide the resets here so you can try them on yours - I won't associate any one reset with a single model because a complete list of which reset works with what model Security DVR simply doesn't exist. Some of these won't make sense based on the buttons available on your unit or your remote. In those cases, just skip that reset procedure.
If you can perform a reset (in other words, if the instructions match what you have available on your Samsung Security DVR and/or Samsung Security DVR Remote), try it, and let us know in the comments if it works and on what model. If you tell us which model Samsung Security DVR you have, along with your results of each reset procedure, we can compile a complete list of reset procedures by model so that it will be easier for those seeking this information in the future to reset their Samsung Security DVR. Also, if you have a reset that you have used and you know works, let us know and we will add it here. I will update the list of Samsung Security DVR resets/recoveries as I encounter them.
So if one of these doesn't work for you, you may want to check back occasionally. In fact, if you leave your model number in the comments and any specifics about your problem, I'll try to get that specific reset for you. For any of these comments, just use the comment section at the bottom of this page - it is checked regularly.
Samsung Security DVR Default Password
For nearly all Samsung Security DVRs, the default password is 4321. If it hasn't been changed since setup, then you can just use that to access the DVR. The default password is included in the reset procedures for completeness. If you have changed your password or access code for your Samsung Security DVR since it was setup, or if you changed it during the initial setup, use that password in place of the default password. The password will be the latest password that was set on the DVR. If no password has ever been set, then it will be the default.
Steps to Reset your Samsung Security DVR

Hello skunkel,
Yes, I believe I can help you. Hopefully these previous admin person did not go nuts with the security thing. But I can help you either way. The least painful method. Approach the copier and view the operator control panel as we are going to go into service mode and delete the admin password. I am about to describe a "fluid 3 step keystroke " function which will put you into service mode. Before we start , locate the "ADDITIONAL FUNCTIONS" button located between the LCD screen and the 9 key pad. Now, press additional functions, then the numbers 2 and 8 simultaneously, then back to additional functions in a smooth three step flow. The screen will change as you have entered service mode. Depending on the configuration of the device you will have several tabs in your display and copier will be at the top. Press copier. A new display appears with several tabs across the top. Press the function tab. New display again, and now press "clear". New display again. Look for "PWD-CLR". Once found, press it. It will be highlited,and then press the "OK" button in the lower right corner. The ok button will indicate you have touched it by beeping or highlighting or both (depends on the model). Then turn the main power off (the actual switch not the button on the op panel. If you are in doubt unplug the machine. After a few seconds re-energize the copier. If the previous administrator merely used a password then it is now deleted and you are home free. If not, then you will need to enter service mode again.......copier........function.......clear..... and then find MMI . Clearing this field will delete ALL customer inputs(IP address, favorites etc). If it is necessary press MMI and then ok. Usually you wont have to do this. But if you do you can have the fun of re-entering all your old settings as it will go back to factory settings.

SOURCE: How reset/remove admin password
You can hack windows if you know how but otherwise there's nothing you can do. You will need to re-install your O/S from scratch and don't forget the password this time. Back up your important files & do a clean install.

You can't. You have to send it back to dedicated micros, unless of course you can use hyperterminal.
You'll have to login as an Administrator for it.
