We have noticed ~15k failed login attempts a day on one of our admin-accounts in the domain.
The source server is found and the event type is "Network", the source is a DC that has not been touched (except WinUpd) for years so a virus seems unlikely but of course possible.
Is there a way to trace exactly what the failed attempts point at? We have recently changed FSMO roles between two other DCs in the domain, maybe that has something to do with it?
You can check the login failed attemps based in audit logon events local computer policy.
use the keyboard shortcut Windows Key + R and type:gpedit.msc in the Run line and hit Enter.
In Group Policy Editor, navigate to Windows Settings >> Security Settings >> Local Policy >> Audit Policy.
Then double click on Audit Logon Events.
From there, check the boxes to audit failed audit attempts and click OK.
There you go! Now you’ll be able to see the complete logon activities (failed l) for your Windows computer.
Please refer this one as well based on event id you can know exactly what the failed attempts point at. : https://social.technet.microsoft.com/Forums/en-US/f49cd4d6-a7d5-4213-8482-72d1d5306dab/windows-server-2012-r2-help-finding-failed-logon-attempts-source?forum=winserversecurity

Assume the following scenario:
I log on terminal server with RDP (Windows Server 2012 R2 or 2016)
Another user connects to my session with "mstsc.exe /shadow" command.
I get the message to confirm this access, and I agree.
Then, after a while I would like to check if my session still being shadowed.
Is there any way to perform this check? Any command, Win32 API, WMI query?
So far, I was only able to find out that rdpsaproxy.exe program is started in shadowed session. That is almost enough, but this program also keeps running when user denies access when prompted to accept initial shadowing request. So detecting presence of rdpsaproxy in check session is not enough to say that somebody is watching me.
You could bind a notification task to the events of Microsoft-Windows-TerminalServices-RemoteConnectionManager/Operational event log:
20503 - shadow watching started
20504 - shadow watching stopped
20506 - shadow control started
20507 - shadow control stopped
All,
I have no idea how Windows service works, just curious when we register a windows service(such as auto run a server after reboot), if it requires a user profile to load info(such as pulling data from somewhere else), what user profile does it load?
Thanks,
You can select what user run each service registered and the system comes with users assigned per service. The most used by the system is SYSTEM.
To check this you have to:
Go to services.
Right click on the desired service and properties.
Go to the Log on tab and check.
If the Local System account is selected the username is SYSTEM which has special permissions on almost all folder and Windows sections including users' profiles data.
By the other hand if you would like to do something special with an specific account you can tell the system the service will start with the account specified. Just make sure to update the password information every time the user change it.
Regards,
Luis
The DC is set up to lock out after three failures however this particular member that has some different applications is getting locked out after one failure. Any ideas what could be causing this to happen?
This mostly happens when the user has logged on to another device with their credentials then changed their password. Now the other device/service is trying to log on/run with the old cached credentials. This has happened to me a few times before because I have tasks running on multiple servers under my credentials and after changing my password (90 days) I forgot to change them on the other machines. Try having the user log out or shut off all devices they have used then reset their credentials. That worked for me. Microsoft also has tools to figure out where these credentials are being used.
I have the following problem: i need to log in a log file somewhere the time at which an incorrect password is tried in an attempt to login in windows 7.
I seached the internet but was not able to find that.
Does anyone know how this is done?
All system login/authentication attempts are logged in the Security Audit Log within the Windows Event Viewer by default. These logs are written by the Local Security Authority Subsystem Service (LSASS.exe). It is possible to analyze these events and filter out the exact information that you want.
Is it possible to start postgres process with a user account that has "administrative" privileges? I am on windows XP.
--Error shown is --- (Not really error, it is a security feature)
The server must be started under an unprivileged user ID to prevent
possible system security compromises. See the documentation for
more information on how to properly start the server.
Current work around is to create normal user and run process under that. What I am looking at is quick way to start database, do some operations and shut it down as part of build process.

Postgres ships with a control program. See details in official documentation
Short answer:
pg_ctl start "args"
