# Troubleshooting

## Windows

### Error while retrieving readers

#### Is the smartcard service running?

The Smartcard service is a Windows service that manages the connection to the eID and card reader. Therefore, this service must be running for you to be able to access the eID. You can check this as follows:

* Open "Windows Services".
* Search for "Smartcard service" as shown in the following screenshot:

![](https://eid.belgium.be/sites/default/files/content/1._smartcardservice_0.png)

Check the following Smartcard service settings (based on the screenshot above):

* The status column for the Smartcard service shows 'Running'.
* The 'Log On As' column shows 'Local Service'.

Are the Smartcard service settings NOT as they should be? Then do whichever of the following two options applies:

**1. The Smartcard service is not running.**

Start the Smartcard service, as follows:

* Double-click the Smartcard service.
* Click 'Start' and then 'OK'.

* Double-click the Smartcard service.
* Select the second tab, 'Log On'.
* Select 'This account'.
* Click 'Browse'.

* Then click 'Check names'.

* The name 'Local service' now appears in the text box.
* Then click 'OK'.
* Leave the password boxes empty.
* Click 'Apply'.
* Click 'OK'.
* Go back to the first tab, 'General', and restart the service.
* Click 'Start'.
* Click 'Stop'.

## DNS probe finished nxdomain error

In some cases there is a possibility that the system is not able to retrieve the domain information, in this case the T1C is not usable. To solve this problem you can follow these steps described here;\
<https://www.hostinger.com/tutorials/fix-dns_probe_finished_nxdomain>

## Error during installation MSI error 2502 or 2503

When installing the T1C the possibility of the **errors** **2502** or **2503** originate from the fact that permissions in the temp folder (C:\Windows\Temp) are not correct, and since the MSI installer relies on this they need to be correct. You need to have permissions next to the administrator rights.&#x20;

You need to have permissions as \<My User> next to the administrator rights.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://t1t.gitbook.io/t1c-js-guide-v3/v3.4.2-1/miscellaneous/troubleshooting.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
