If you have chosen the manual provisioning method, you must configure access permissions and settings individually on managed servers. Two general methods for configuring these settings are available:

Manual application of IPAM GPOs: With this method, IPAM GPOs are created but are not automatically applied to managed servers. Application of GPOs is done manually by adding managed servers to GPO security filtering. To use this method, first perform the steps in Create IPAM Provisioning GPOs. When you have created these GPOS, configure security filtering by performing the steps in Configuring IPAM GPO security filtering.
Manual configuration of individual settings: GPOs are not used with this method. Instead, access settings on each managed server are configured manually by an administrator. Steps to configure these access settings are provided in this topic.

For more information about choosing an IPAM provisioning method, see Choosing a provisioning method.

Membership in the Domain Admins group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).

Manually configure managed DC and NPS server access settings

Use the following procedures to configure IPAM access settings on a managed domain controller or NPS server. If the server is also a managed DNS or DHCP server, and you have previously enabled IPAM access for these services, you have already enabled the necessary access. If you have not already enabled IPAM access using Windows Firewall and the Event Log Readers security group, perform the following procedures:

A summary of required settings is provided in the table below.

Setting Type	Setting Name	Function
Inbound firewall rule	Remote Event Log Management	Audit authentication events
Security group	Event log monitoring	Audit authentication events

Configure Windows Firewall on a managed DC or NPS server

Use the following procedure to enable access by the IPAM server to inbound firewall ports on a managed domain controller or NPS server. If the managed server becomes unmanaged, delete these inbound firewall rules. All of the following procedures are performed on the managed server.

To configure Windows Firewall on a managed DC or NPS server

On the Server Manager menu, click Tools and then click Windows Firewall with Advanced Security.
Right-click Inbound Rules, and then click New Rule. The New Inbound Rule Wizard will launch.
In Rule Type, select Predefined, choose Remote Event Log Management from the list, and then click Next.
In Predefined Rules, under Rules, select the checkboxes next to the following rules:
- Remote Event Log Management (RPC-EPMAP)
- Remote Event Log Management (RPC)
Click Next, choose Allow the connection, and then click Finish.
Close the Windows Firewall with Advanced Security console.

Configure security groups on a managed DC or NPS server

To access configuration data and server event logs, the IPAM server must be a member of the domain IPAM Users Group (IPAMUG). The IPAM server must also be a member of the Event Log Readers security group.

Warning

If you have already created the IPAMUG security group in Active Directory and added the IPAM server as a member of the group, it is not necessary to perform this procedure again. The steps to add the IPAM server to the Event Log Readers security group is different on a managed domain controller than a managed NPS server. Both procedures are provided below. If the server is both a domain controller and NPS server, perform the procedures for a managed domain controller.

After performing these procedures, refresh the server access status for the managed domain controller or NPS server in the server inventory view on the IPAM server.

To configure the IPAMUG security group

On a domain controller, click Tools on the Server Manager menu, and then click Active Directory Users and Computers.
In the Active Directory Users and Computers console tree, right-click the Users container under the managed DHCP server’s domain, point to New, and then click Group.
In the New Object – Group dialog box, under Group name, type IPAMUG.
Under Group scope, select Universal and under Group type select Security, and then click OK.
Double-click the IPAMUG group and then click the Members tab.
Click Object Types, select the Computers checkbox, and then click OK.
Under Enter the object names to select, type the name of the IPAM server and then click OK.
Verify that the correct IPAM server is displayed under Name and then click OK.

To configure the Event Log Readers security group on a domain controller

On the managed domain controller, click Tools on the Server Manager menu and then click Active Directory Users and Computers.
In the navigation tree, click the <domain>\Builtin container and then double-click Event Log Readers.
On the Members tab, click Add.
Under Enter the object names to select, type IPAMUG, and then click OK twice.

To configure the Event Log Readers security group on an NPS server

On the managed NPS server, click Tools on the Server Manager menu and then click Computer Management.
In the Computer Management navigation tree, click Local Users and Groups and then click Groups.
In the list of groups, double-click Event Log Readers and then click Add.
Under Enter the object names to select, type IPAMUG and then click OK.
Verify that <domain>\IPAMUG is displayed under Members and then click OK.
