Running APBackUp as NT/2000/XP service

To run APBackUp as a service you can use any other service that can start a program with parameters, or srvany.exe from Microsoft NT Resource Kit, included in the distributive. This service can start applications with parameter "service", so that the application will work even if no user is logged in. To configure the application to run as a service use "Program options" -> "NT/2000 service". This command will install the service "APBackUp_Starter". To stop using service use button "Delete service"

If you install service under LocalSystem account (default), then the program will not have access to network resources. If you need to connect to network resources, you will have to install service under other account.

That is from Microsoft Win32 SDK:

“The LocalSystem account is a predefined local account used by system processes. The name of the account is .\System. This account does not have a password. If you specify the LocalSystem account in a call to the CreateService function, any password information you supply is ignored.

A service that runs in the context of the LocalSystem account inherits the security context of the SCM. It is not associated with any logged-on user account and does not have credentials (domain name, user name, and password) to be used for verification. This has several implications:

·      · The service cannot open the registry key HKEY_CURRENT_USER.

·      · The service can open the registry key HKEY_LOCAL_MACHINE\SECURITY.

·      · The service has limited access to network resources, such as shares and pipes, because it has no credentials and must connect using a null session. The following registry key contains the NullSessionPipes and NullSessionShares values, which are used to specify the pipes and shares to which null sessions may connect:

·      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ LanmanServer\Parameters

·      Alternatively, you could add the REG_DWORD value RestrictNullSessAccess to the key and set it to 0 to allow all null sessions to access all pipes and shares created on that machine.

·      · The service cannot share objects with other applications, unless they are opened using a DACL which allows a user or group of users access or NULL DACL, which allows everyone access. Specifying a NULL DACL is not the same as specifying NULL, which means that access is only granted to applications with the same security context. For more information, see Allowing Access. · If the service opens a command window and runs a batch file, the user could hit CTRL+C to terminate the batch file and gain access to a command window with LocalSystem permissions“
