NLB in Unicast Kills networking

-

afternoon all,

i getting strange issue nlb configuration , wondered if had seen before. building cas array ontop vmware cluster. using dell switches, having configure in unicast mode. have followed guides vmware , have created dedicated portgroup has 'notify switches' set 'no'. have attached nlb network interfaces dedicated network.

i have configured nlb between 2 hosts, using 'nlb' network ip addresses cluster members. nlb comes online, failover works etc.

i reboot server, , kind of networking dead in water. able ping other boxes. dns, ad etc not work. if disable , re-enable nlb adapter starts working again.

i have configured binding order lan card first.

any ideas?

thanks

paul
