IP Conflict

I am running a couple of Servers, one DC/AD, DNS (Server2008) and one server
which I use for applications (Server 2003). The server which I use for an
application has two Network cards with the IP's 192.168.0.77 and .78
I am getting an error that I have an IP conflict with the IP .77 and I am
sure there is no other PC or component configured with IP .77
How can I make sure that there is no other IP.77 on the network and also I
am right that there is no dublicate IP address what could cause this.

Hello Somchai,

Why are you using 2 ip addresses form the same subnet? Use one NIC or check
if a teaming software exists for the server. The conflict is tha the servername
"exists" with the other ip address.
