dual network cards

can anyone shed any light on why i get the following message when trying to add an SNMP / network device monitor for a server;

Unable to add the Interface for IP Address 10.80.0.90. Kindly check whether the machine has dual interface.If it has dual Interface try adding with the another IP Address.

The server was deleted from appman and added back at a later date. I can add a monitor fro the server with WMI monitor but I get this error if I try to add SNMP monitor or Oracle monitor.

The server does have dual nics which are teamed under the one address and so there isn't another IP address i can reference the server with for appman to connect.

Any help greatly appreciated.
