DNS server WMI permissions

The following section details the permissions required for IPAM users to monitor DNS servers.

Enable an account for WMI

A DNS server administrator account that can make changes on the DNS server is required to manage DNS servers. If you have a stand-alone DNS server, you can use a local administrator account configured for WMI access.

Administrator accounts are configured to make DNS server management tasks by default. For an AD and DNS setup, this is an account with full DACL (discretionary access control list) with remote WMI management enabled

Grant read-only access to non-administrator accounts for IPAM DNS monitoring

To poll the DNS server without an administrator account, you must add the user to the DNS Admin group. The account must have Read/Write permissions for DNS management so the account is able to write itself to the DNS server as a zone transfer server. Administrators can specify the rights of a user within their account settings to have just read only access to the DNS portion of IPAM.

Enable an account for WMI

Use the DNS Server Administrator account based on your network configuration.

  • In Standalone DNS, administrators are configured to make DNS server management tasks by default.
  • In a AD+DNS setup, use the account with full DACL to manage the DNS Server. The account must have remote WMI for management enabled.

The following steps detail how to use a non-administrator account.
