Cisco 1000V and MS WLBS in unicast mode

hi out there

We encountere a serious problem when we migrated the second terminalserver to our VMWare center running ESXi 4.1 - wlbs wasn't working in unicast mode - i looked a bit in the mac.table of the VSM where the problem probably show up - we have 2 terminalserveres running win2k3 with termibnalservers in wlbs/nlb unicast mode - the nlb-i/if for eacht ts is connected to veth23 and the second server is veth26 - the mac-adresse for the cluster is 02bf.ac15.9513 but this is only added on Veth23

Nexus1000V# sh mac addr int ve 23 Legend:

         * - primary entry, G - Gateway MAC, (R) - Routed MAC         age - seconds since last seen

    VEM      VLAN      MAC Address      Type      age     Ports

---------+---------+-----------------+--------+---------+----------------

      12      2001     0201.ac15.9513    dynamic   0       Veth23

*    12      2001     02bf.ac15.9513    static     -      Veth23

  Nexus1000V# sh mac addr int ve 26 Legend:

         * - primary entry, G - Gateway MAC, (R) - Routed MAC         age - seconds since last seen

    VEM      VLAN      MAC Address      Type      age     Ports

---------+---------+-----------------+--------+---------+----------------

     12      2001     0202.ac15.9513    dynamic   0       Veth26

Nexus1000V#

hereby all the load is directed to the first TerminalServer on Veth23 - not to the second on Veth26 - is there a simple way to solve this problem ?

best regards /ti
