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.  Not an acl, other ip devices in same segment can be  pinged successfully. All ip addresses are assigned via dhcp server.  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  can ping other 10.1.x.x devices.

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.
The problem began when we changed dhcp servers, but only on two devices.
Not sure if somewhere on the network only those two ip addresses still remain in a table of some sort.

From the devices default gateway (router), can you ping theses devices?  If you look in the routers ARP table, is the MAC address correct for the two IP addresses?  The Windows Firewall isn't running on these devices is it?
