While your scopes may show as 90% free, are you taking address exclusions into account? Even a 90% full DHCP scope would make me consider deploying additional scopes or expanding the existing one.

I looked at each scope plenty of free addresses. I have two deactivated scopes would that turn the icon blue?

I have two domains controllers. They both are having the same issue. <br />
<br />
When I log into DHCP the icon is green and looks normal<br />
<br />
When I expand the icon it turns blue with an exclamation mark<br />
<br />
I looked at display statistics for all scopes and there is plenty &nbsp;90% free on all scopes. <br />
<br />
I know Microsoft says the below about the blue icon with exclamation mark......<br />
DHCP server alert. No addresses are available from server scopes because the maximum (100 percent) of the addresses allocated for use are currently leased. This represents a failure of the DHCP server on the network because it is not able to lease or service clients<br />

DHCP Scope turns blue with exclamation mark

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
