Event ID 4319 on Multihomed server

My event viewer is filling up with these errors from PCs locally and on other
subnets on our network. I'm running DNS and WINS on this server. I'm also
getting these messages on our other three servers, but not as many. All of
our servers have two network cards and all of them are on the same subnet.
Our remote offices / subnets are run through Sonicwall VPNs which have their
own DHCP server.
I've verified that the users are not logging in twice and I've run Scavenge
several times on the DHCP server.
Any other ideas?
 
In addition the the details below I have discovered that one of the errors
was coming from 192.168.3.107 about every hour last night. This morning I
changed the IP to obtain from the local DHCP server on the Sonicwall router.
Now I'm getting the same errors from that IP as well. Here is the original
error message:

This "All of our servers have two network cards and all of them are on the same subnet" could be the problem. you should not setup them in the same subnet.
