# DNS Service Record for Agent Autodiscovery

In order for agents to find the SSPR 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                                           |

| Protocol    | \_tcp                   |                                                       |
