# DNS Manger not usable

When you see this error in the storefront when you open the DNS manager:

```
Da Sie scheinbar nicht mehr unsere eigenen Nameserver verwenden, steht die DNS Verwaltung nicht mehr zur Verfügung und muss über Ihre eigenen Nameserver verwaltet werden.
```

{% stepper %}
{% step %}

### Define a default NS Set

You have to define one [nameserver set](https://docs.hostware.io/domains/nameserver-sets) in the hostware settings. Define a set with your default nameservers
{% endstep %}

{% step %}

### Open Nameservers

After you have done that, open the "nameservers tab" on the domain in the storefront.
{% endstep %}

{% step %}

### Use DNS Manager

hostware will detect that the NS are related to the NS-Set and will release the DNS Manager.
