# Wireguard adapter is not created on Windows Server 2019 occasionally when joining with a multiple ne

Description

{% hint style="info" %}
This is re-produced on Windows Server 2019.

On Windows Server 2019, when joining networks with a multiple-network enrollment key, sometimes the Wireguard adapter is not created properly.
{% endhint %}

## Reproduce steps

{% stepper %}
{% step %}
Create two Netmaker networks.
{% endstep %}

{% step %}
Create an enrollment key and select both of the two networks.
{% endstep %}

{% step %}
On a Windows Server 2019 machine, install netclient and join the networks with the enrollment key created in the previous step.
{% endstep %}

{% step %}
Observe that the network might not be available and it could not connect to other hosts.
{% endstep %}
{% endstepper %}

## Analysis

{% hint style="info" %}
Somehow on Windows Server 2019, after installation and joining the networks with a multiple-network enrollment key, sometimes the Wireguard adapter is not created properly. This results in the network configuration not being ready, and the Netmaker network being unavailable.
{% endhint %}

## Workaround

{% hint style="warning" %}
Run the following command again:

{% code title="Retry join" %}

```
```

{% endcode %}

Re-running the join command updates all configuration and routes successfully. The Netmaker network should then work as expected.
{% endhint %}
