I have problem with creating service that has access to files on network disk.
Service must have admin rights and it will be run by users that don't have admin privileges.
I send path as UNC
and file is seen by service but it return ACCES_DENIED errors when try to open or do anything on Network drive.
When I run my service as server , everything works fine.
I try to find answer but everywhere I can found only partial answers that do not help me at all.
========
I read that standard service logged as SYSTEM can't have access to network.
So i tried to log id as
NetworkService, LocalService
It didn't work. After run it as one of those user my service can't save files on c:
Some kind of admin account.But I didn't manage to success on that.
Actually logged user.
I don't know how to get password for current user.
Still this will not work for user without admin rights.
========
Please tell me what can I do?
There are plenty of Services that use somehow network resources. How do they do that?
You need to configure your service to run as a user which has sufficient rights. In this case you are looking for rights to network shares. Typically that's going to need a domain user with appropriate rights. Normally you'd ask your network manager to create a dedicated user account for the purpose.
You appear to be labouring under some false information as to how services work. You talk about running the service under the account of the logged on user. Remember that services run when there are no users logged on. And remember that there may be multiple logged users at any point in time.
For me, the port was getting blocked through firewall, I had to add a inbound rule and specify the port which i was using in my application. This way firewall did not blocked my port for outgoing connections.

Im a newb to AWS, so please go easy on me. We currently just spun up a custom Windows 10 instance in AWS. I was able to login via RDP successfully, but I'd like to create a new user within the instance so they can login with a different user account using RDP. Any thoughts would be much appreciated.
Okay, After your response to my first, I think I see what you are asking. Plase watch this video:

Download the RDP. Save it. You can then Edit the .rdp and enter the user name and password you created in Windows.
You can create users in the User Management Console in Windows. Ensure they have the rights needed (Remote Desktop User, Administrator, etc).
Enjoy!
Once an Amazon EC2 Windows instance has been launched, it is just a normal Windows computer.
Therefore, you should use use the standard Admin tools to create the user on the Windows computer, with their own username and password.
It is also recommended that you change the random Administrator password after initial login, or (even better) connect the instance to Active Directory or whatever standard authentication system your company uses.
Technoob here. I just figured out why all of you are having trouble. You need to go to the security group the machine is a part of and open port 3389 to your public IP address (ipchicken.com works). Enjoy
If you are trying to connect from another computer then you have to change the inbound rules.
Go to the security groups of your instance. Go to the inbound rules. Add ipv4 and ipv6 as a new rule and apply it. Download the RDP File and try to connect again. It worked for me.
I was installing the filebeat application and I noticed that I needed to run powershell as administrator in order to install them. When I checked the service using wmic service get name,startname,status it showed Local System. I'm wondering what this account is as this is neither the user account or the administrator account. Will this always be the case when I install services as administrator? What is the difference if I install it as a normal user and as administrator?
In any case, I've set this service to start automatically when windows start. Would this service start only when the user I used to install it logs in or will it start regardless of which user logs in?
OK, let's unpack that one by one, in no particular order:
Only a user with administrator rights can install a service.
Services that are configured to start automatically are started as soon as Windows is up and running; Windows does not wait until somebody logs in. It makes no difference to the service who the logged-on user is, or whether anybody is logged in at all, unless the service application itself has been explicitly programmed to check.
The program that installs the service decides what account the service uses to run. Windows doesn't care what user account was used to install the service, it doesn't even keep track.
If the program that installs the service wants it to use an ordinary user account, it must know the password for that account. There are various special accounts that a service can run in, these accounts do not require a password. One of these special accounts is Local System.
Local System is the highest-privilege service account in Windows; it has all the same rights as an administrator, and can do things an administrator can't. Local System is also the account that the user-mode part of Windows itself runs in, roughly equivalent to the UNIX root account except that it doesn't have a password.
Additional notes, for completeness:
One alternative to Local System is for the service to run as Local Service or as Network Service, which are non-administrative service accounts. The only difference between the two is that if the computer is joined to an Active Directory domain, the Network Service account has network access to other machines in the domain and the Local Service account does not.
It is also possible to configure a service to run in a special service account that is unique to that particular service. This is mostly useful if you want the service to have access to a particular file or folder, but do not want to give it administrator rights.
Nitpickers corner:
It is I believe technically possible to reconfigure Windows to allow non-administrators to install services, but this is not supported and would be a Very Bad Idea. If you did, though, it would still make no difference who installed the service. Windows doesn't record this information.
I'm writing a Windows device driver for a custom USB device, but am having trouble opening the device from my user program (using CreateFile) when the user program is run as a domain user. If I run as a local user, or as an administrator (or 'Run As' administrator) I can open the driver fine, but as a domain user GetLastError returns 5 (access denied).
I originally had this problem with local users too, and found I had to add the following SDDL entry to the .inf file, which solved the problem for local users:
HKR,,Security,,"D:P(A;;GA;;;SY)(A;;GA;;;BA)(A;;GRGW;;;BU)
From this reference:
http://msdn.microsoft.com/en-us/library/windows/hardware/ff563667(v=vs.85).aspx
When I discovered that domain users did not have access I thought that simply adding them to this SDDL entry would give them access, but it doesn't seem to work: I still get access denied. I've even tried extreme solutions such as giving all users (everyone (WD), unauthenticated users etc.) full access, but this doesn't work either, which makes me think the problem lies elsewhere; i.e. something else is denying domain users access which takes precedent over the permit in the SDDL entry in the driver inf.
So my question is, what am I missing that is required to give domain users (or all users) access to connect to the driver? Or are there any other solutions to this problem (such as connecting to the driver as a service and then accessing this service from the user program)?
HKR,,Security,,"D:P(A;;GA;;;WD)"
set everyone can access, try it!
I am working on the examination system and need to implement the following scenario:
User ( standard windows user ) completes the exam and then it is saved on the network share.
For security reasons the share does not have permissions for this user account. So I use impersonation API ( LogonUserEx, ImpersonateLoggedOnUser, RevertToSelf).
It all worked fine when the user with which I do the impersonation had admin privileges on the
local computer but the requirements are that it will be standard user.
With standard user the share is not visible. When I log in interactively with this user the share is visible and writable. So I assume that the standard user can not mount share when not logged in interactively. Is this correct? Is there a workaround?
The only time my code runs with elevated privileges is during the setup of the software.
I thought about using WNetAddConnection2 API but I need the share to be mounted to
this "hidden" user profile and not the administrator one that runs the setup.
I am currently trying to access a network share from my machine programaticaly using vc++ 6.0. I am using WNetAddConnection2 to connect to a share using my credentials.
I am facing the following problem:
Consider the case when there are 2 users trying to access the same remote share from same machine one after the other. Now once a user logins, the other user is not able to login into the share using his credentials until the 1st user logouts.
Also if the 1st user logs onto the remote-machine's root share, then the other user is not able to access anyother share on that machine.
Please let me know if there is any workaround for the same.
Thanks in advance
The answer depends on if the 1st user still needs access. If they don't, then call WNetCancelConnection2(). If they do, Keith Brown in his "Programming Windows Security" book has a trick of calling LogonUser() to establish a new logon session, which creates a new SMB "port" to avoid the conflict. After impersonation, your thread will be able to connect using different credentials.
