"Unknown users" listed in properties and safety of a folder
PROBLEM: "unknown users" are listed in the properties/security of a folder.
I have Windows 7, 64-bit.
The properties/security box from my "C:\Users\[my name]" folder lists two known as users
"Account unknown (S-1-5-21-879640176-2077098734-2292519611-1001).
and "Home Users", more legitimate users 'SYSTEM', 'Administrators', and
"[my name]."
After deleting the computer Acct limited, the 2 users are still listed.
'S-1-5-21-879640176-2077098734-2292519611-1001' is not found by the Yahoo Search
Engine. Windows specific engine search folder 'C:' and 'Users' research essentially
indefinitely. For the folder named after me is nothing.
Especially regarding'S-... ', this is the result of malware? Would the deletion or the other or both of these
Users of harmful effects?
Thank you.
These inscriptions refer to the accounts that you have deleted from your computer. They are of no consequence, and they cause no harm.

Hello networktec,
1. you have access to the files and folders on the Windows partition when you work inside VMWare?
If the security on the files/folders tab will then a user/group account that has the username inside VMware listed list. This could be the reason that the user name is created. Unknown user can be a part of the Vmware software.
However, I suggest that you post your question to the VMware community to see if it is the cause of the unknown account:

We created an unknown accout on my laptop Windows 7 did it probably a malware or some kind of virus. This unknown account took all permissions including the special permission. In this way, he blocked my access to a lot of my documents and multimedia files. This unknown account does not appear in the list of user accounts. Thus, it cannot be deleted or modified/restricted. I tried to detect this virus/malware microsoft security essentials and MacAfee antivirus programs. The two could not detect something. Any help?-ERC

b. right-click and select Properties. Click the Security tab.
c. If it is there, then click on the Edit button, then click the Remove button.

unknown user may have reset my administrator and password of the user access.
Woke up at 3:00 to hear the computer by clicking on, running 2 programs, one was Majic Jack the other did not. went to user accounts to search for an unknown user. Remove the user, VRI.net or something like that, but the first google
He and found to be a developer software any. restarted after 55 keep me informed but wouldn't show it to them. I also changed the Welcome screen options, then after reboot shows my user name, but won't accept my password. Can it be delivered starting CMD line in mode sans-echec? and more importantly, how to prevent this in the future?Whenever someone thinks that their computer has been compromised, I suggest you have a local professional come on site to diagnose and repair. Respectfully, a regular user of the end won't know what to look for and how to secure the computer correctly.
As for your password:
If you have forgotten your password, if you have another user who has administrative privileges account you can log in to that account and change the password of your account of origin of the user accounts applet in Control Panel. If you do not have another account like this set upwards or that you do not have the password which you will need to log on to the built-in Administrator account. In XP Home, start the computer in Mode safe. This, by repeatedly pressing the F8 key as the computer starts. This will put you in the right menu. Navigate using your arrow up; the mouse does not work here. Once in safe mode, you will see the normally hidden administrator account. The default password is white.
In XP Pro, you don't need to go to Safe Mode. In the home screen, do Ctrl-Alt-Del twice to get the classic Windows logon box. Type in "Administrator" and the password that you assigned when you set up Windows.
If you reset the password of the account administrator integrated into house or have Pro and don't remember the password, use NTpasswd to change the password of the built-in to a white administrator account. Download the bootable CD .iso image file, burn with third-party burning software such as free ImgBurn , Nero or Roxio. Burn as an image, not in the form of data. Start with the media that you have created. You need to maybe change the boot order in the BIOS or obtain a menu of boot command temporary with the pressure of a special key. NTpasswd will run. Follow the instructions carefully.

Then, go to the user accounts applet in Control Panel and set passwords that you remember and other changes. MS - MVP - Elephant Boy computers - don't panic!

Identify and remove an unknown user
Troubleshooted diagnosis of Windows I have several users on my computer, and this slows down the performance of the computers. How can I; ((1) to identify the user and remove 2) it?
Please note that my computer skill level is low. =)
Have multiple users on your computer will not slow down it. Something is happening, but you have not provided any information to solve problems. To see what users on your computer are:
1. go in Control Panel > user accounts and note what you see.
2 activate the ability to see the files hidden Panel > Folder Options > view tab. Then navigate to C:\Users and take note of what you see.
Post back with this information.
See the general 'slow computer' Troubleshooting below. However, since you say that your computer skill level is low, it would probably be best for you to take the machine to a local professional reputable (not a type of BigComputerStore/GeekSquad of the place). If you can't / won't do it, then please provide more information in your next post by:

unknown user Skype with my email
[The update by the moderator topic title should be more descriptive. [Original topic title was: 'unknown user Skype']
Today at approximately 11:26, a Skype user, I've never added before is appeared on the list of my friend? Their display name is set to one of my emails (which is not registered to this Skype account including) and to my knowledge has no connection with the account that I currently use.
I called and texted. The call never crossed and the message sent, no more. They have no user name in their info, only 'messenger' Panel, where the username is supposed to be.
Anyone know what it is? It could be a kind of robot, but I don't know because this email is not connected to it. This could be because I have connected to the Skype account that the bot is associated on this computer, but I'm not sure.
Screenshots down below.
Any help or ideas for what this might be is greatly appreciated.

Unknown error in the network and sharing Center
When I opened my network and sharing Center where the active networks would be just said
'Unknown '.
and
"The account specified for this service is different from the account specified for other services running in the same process"
If I open Services.msc and check the list of networks and Network Location Awareness service, both are on automatic and both connect as a network Service.
Network list service does not work and does not give the error:
Error 1079: The account specified for this service is different from the account specified for other services running in the same process
I'm connected to my home network and have internet access and also a local access to other computers, it's just not appearing is not on the network and sharing Center.
A result of this is that some of the metro apps don't report any internet connection and will not start. I currently now disconnected my microsoft account on the computer and use a local account, but the problem is still there.
I also tried
netsh winsock reset
from an administrator command prompt but no change.
Can anyone help?
Hi Andrea,
Please keep us updated.
This can be shown because of missing or corrupted system files. This is why I would recommend running the System File Checker tool, which is a Windows utility that allows users to find corruptions in Windows system files and restore corrupted files.
To do this, click Start, type command or cmd prompt in the Search box, right click invite, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.
At the command prompt, type the following command and press ENTER:
sfc/scannowNote: Do not close the command prompt window until the audit is completed 100%. The results of the analysis will be posted when this process is complete.
I hope this helps. Please feel free to answer in the case where you are facing in the future other problems with Windows.

The first time, it is managed it can increase the free space on the drive by something like 4 to 5 GB. The free space on the drive back if you run after the subsequent monthly updates is not so dramatic, but significant,
Whenever you launch this new feature when you turn off the system is reconfigured when stopping and when the computer is started then. This is similar to what happens when you install several updates of windows. However, the configuration can take several hours, which is much longer than when you have only updated. It is important not to press the power button configuration is underway. If you have a laptop, make sure that the computer is connected to a power source. Also the second time that you stop the process happens again, but this time after that configuration there is a reference to cleaning and when completed the computer automatically restarts on its own, without any intervention from the user. When the computer has restarted the computer is available for use.
No documentation I've seen warns the user what to expect, and my first reaction was that something had gone wrong. It was not and should not as long as the user not involved not.

Search ACS 4.2 order unknown user from database
Hello
I have several user databases in the search order for the unknown user policy. Ignoring the manual (http://www.cisco.com/en/US/partner/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/user/guide/UnknUsr.html#wp277530), which States that, after the failure of authentication from the first database (Windows) the ACS does not continue to look for the second database, a RADIUS server. I see that, with the failure in the first user, database stops the ACS research and fails to the user authentication with an authentication failure code "external DB password invalid.
Documentation not going or is this a bug in the ACS v4.2.1? How can I make the ACS to continue to seek the second database user?
Hello Roberto,.
If the external database returns an invalid username/password, then it is intended for ACS is not to check the following data in the sequence and the failure of authentication:
"For authentication requests, ACS applies the unknown unknown user policy to users. ACS does not backup to the known or discovered users authentication failure unknown when user authentication support. »
If you want that ACS to verify the following database, even if a response from the invalid username/password has been received, you will need to explicitly set this on the external Windows database configuration page, in the section entitled 'Strategy for the unknown user' (but on the database configuration page specific Windows, not covered by the unknown user policy) :
In addition, on the previous screenshots, I could see that you have configured both as a result of database:
Windows database
RADIUS Server token
So we may be running into a situation where the authentication method used is not supported by the tokens, Radius servers, and therefore impossible to check the second database in the list:
Kind regards
Fede
