# SiteServer

<img noZoom src="https://mintcdn.com/specterops/tTIczgde9H07oLXf/assets/enterprise-AND-community-edition-pill-tag.svg?fit=max&auto=format&n=tTIczgde9H07oLXf&q=85&s=ad49a576589f4d2a8081df77d07fdf56" alt="Applies to BloodHound Enterprise and CE" width="482" height="45" data-path="assets/enterprise-AND-community-edition-pill-tag.svg" />

## Representation

The SiteServer node represents an Active Directory `server` object under a site's `Servers` container. A [ServerIs](/resources/edges/server-is) relationship connects it to the corresponding [Computer](/resources/nodes/computer) object through the directory object's `serverReference` attribute.

By default, a SiteServer linked to a domain controller is classified as Tier Zero / High Value. This lets BloodHound surface the impact of a compromised [Site](/resources/nodes/site): a malicious GPO linked to the site can apply to the domain controller represented by the SiteServer.

## Node properties

The node supports the properties of the table below.

<Note>
  Properties which are blank/null will not be shown in the Entity Panel.
