Is the default gateway set correctly on the two 10.1.x.x devices that aren't working?

Yes, the ip address, subnet mask, and default gateway are all set correctly.<br />
The problem began when we changed dhcp servers, but only on two devices.<br />
Not sure if somewhere on the network only those two ip addresses still remain in a table of some sort.

We have two isolated static ip devices can be pinged from the router and main switch, but cannot be pinged from other segments of the network. &nbsp;Not an acl, other ip devices in same segment can be &nbsp;pinged successfully. All ip addresses are assigned via dhcp server. &nbsp;Is not a duplicate ip address, because the nic is working and responds to a ping from some segments of the network. ex: 10.3.x.x cant ping only those two 10.1.x.x devices, but &nbsp;can ping other 10.1.x.x devices.

Can't ping 2 ip devices, can ping others in same segment.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

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).
