hello MS team,

i developed a windows service in C# using VS 2019 its task get ip address and send it in txt file to local driven of my computer, until now its run perfect.

but when i execute this windows service to other computer and change destination to protected local network access become denied, however vbscript run normaly and can copy any folder and files to same network with my acount already saved in this computer.

my question why windows service doesn't use the same account to grant access to network as vbscript ?

what is the best solution to solve this issue ?

thanks in advance.

Hi @Fouad Allali , Welcome to Microsoft Q&A,

When a Windows service runs, it usually runs under a specific user account, called a service account. By default, services often run under built-in accounts such as Local System or Network Services, which may not have the necessary permissions to access network resources.

Here are a few things you can try to resolve the issue:

Change service account:

Open the services window (services.msc) on the target computer.

Find your service, right-click and go to Properties.

In the Login tab, change the account under which the service is running. You may want to use a user account with the necessary network permissions.

Grant network access to the service account:

Make sure the account running the service has the necessary permissions to access network resources. This includes share-level and file-level permissions.

Use UNC path:

Use UNC (Universal Naming Convention) paths directly in your code instead of relying on mapped drives. For example, use "\server\share\folder" instead of the mapped drive letter.

Note: Storing credentials in code can create security risks. Please use caution and consider safe alternatives.

Check Group Policy:

Make sure there are no group policies that restrict access to service network resources.

Run the service as a specific user:

In Visual Studio, go to the project properties and navigate to the Debug tab. -Set the "Launch as user" option and provide the necessary user credentials.

Keep in mind that security considerations are critical, and it's important to follow best practices to avoid storing sensitive information like passwords in your code. Consider using a secure method to handle credentials, such as using Windows Credential Manager or another secure storage mechanism. Additionally, test any changes thoroughly in a controlled environment to ensure they do not introduce security risks or unexpected behavior.
