Setting Virtual Server to Load balance Windows DNS Server.

can you explain how would i do this please.

i thought you are saying health monitor still marks pool member (dns server) up even the dns server is shut down, aren't you?

if yes, i think you may have to capture the health monitor traffic between non-floating self ip on bigip and the dns server ip to see why the monitor still marks the dns server up.

 tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x and host y.y.y.y and port 53 -v

x.x.x.x is non-floating self ip on bigip
y.y.y.y is dns server ip
