SMB Access Denied in Java and Node.js Despite Successful CMD Connection with Service Account

Question

I'm experiencing an issue with accessing an SMB share in both a Java application and a Node.js script. When I connect to the SMB share via CMD using a specific service account (username and password), it works flawlessly. However, when trying to access the same SMB share in my Java (using JCIFS) and Node.js applications with the same service account credentials, I encounter an "Access is Denied" error.

Here's what I've tried so far:

• Confirmed the correctness of username, password, and domain in the Java and Node.js applications.
• Checked SMB server permissions for the service account.
• Increased logging level in JCIFS to gather more details, but couldn't pinpoint the issue.
• Looked through JCIFS documentation for any potential misconfigurations.

It's puzzling why the access is successful via CMD but fails in both Java and Node.js. I'm attaching screenshots of the error and relevant code snippets for clarity. Any insights or suggestions on what might be causing this issue and how to resolve it would be greatly appreciated.

Thank you!

        return baos.toByteArray();

and here the log

I have no more ideas to solve this problem I tried with or without domain name
