# DNS Service Record for Agent Autodiscovery

{% embed url="<https://www.youtube.com/watch?v=OQQmCEinH6Q>" %}

In order for agents to find the SessionLimit Server dynamically, a service record must be created on local DNS servers. This record must be created manually and added to the **\_tcp** folder in the local domain zone.

1. DNS management interface opens (dnsmgmt.msc),
2. Active Directory Zone is expanded,
3. Enter the **\_tcp** folder,
4. Click "**Other New Record**" from the Action menu or right-click menu.
5. Select "**Service Location (SRV)**" from the window that opens and click "**Create Record**".
6. On the "**New Service Record**" screen, information is filled in as follows.

| Field       | Value                   | Description                                                |
| ----------- | ----------------------- | ---------------------------------------------------------- |
| Service     | \_seslimv2              | Mandatory and cannot be change.                            |
| Protocol    | \_tcp                   | Mandatory and cannot be change.                            |
| Port Number | 443                     |                                                            |
| Host        | servername.*domain.com* | It is the server where the SessionLimit role is installed. |
