I cannot ascertain what ratio the servers without WMI have been given. i understand it is 1.
The node is not returning SNMP data in the correct format. If the BIG-IP system cannot interpret the data returned by the SNMP DCA monitor, it sets the weight of the node to 1.sol9125: Overview of Dynamic Ratio load balancing

e.g.
200.200.200.101 is linux without wmi agent, 200.200.200.103 is windows 2003 with wmi agent
