# DNS Setup

ABit software products support a DNS lookup option for clients to auto discover the server. This works using a SRV record on your DNS server.

### Create DNS record for product.domain (eg servsched.abit.local)

This is an optional step but recommended step. By providing a DNS name you can easily direct users to [http://servsched:8090](http://servsched:8090) for client installation.

- Type set type=all, and then press ENTER.
- Type \_servsched.\_tcp.{Domain\_Name}, where Domain\_Name is the name of your domain, and then press ENTER.

```shell

_servsched._tcp.{domain}
```

# Client setup

New installations will automatically have “\[AUTODISCOVER\]” as the server hostname. To transition an existing device. This hostname needs to be changed to “\[AUTODISCOVER\]”

### Manual update

Select Options -&gt; Application Servers and change the hostname to \[AUTODISCOVER\]

### Client IP Address Changes via Group Policy

Using a group policy via Active Directory is the recommended way
