NLB on hyper
Today i deployed a NLB cluster on a window server 2008 R2 them are some VMS running on hyper-v R2 base on windows server2008R2 to achieve Network balance and fault tolerance for a certain production works with IIS.I prepared 2 NICS on each NLB node VM serverand planed to launch a NLB cluster work in unicast mode. Everything
is ready. But unlucky accident is always happened when we are enjoying every proceduewhich processed as sucessful as our image. It is not a exception for the case. Yes, like some novel it contains involvedplot.
Ok, long story to short. The problem message told me some message that cluster ip information and the dedicated ip imformation can't configure in TCP/IPproperty and with a error code (sorry, forget to save the code).
Finally i foud a solution work around the issue. In fact , it is very simple ,just open MAC spoofing feature at VM setting of hyper-v Of windows server 2008. The same problme had not encountered in version windows server 2008 RTM.
The following is interesting document about MAC spoofing of hyper-V r2.
