Hello,
We have new Windows 2008R2 domain installed, and two node nlb cluster for MS Exchange OWA in Multicast mode. Every server runs as VMware virtual machine. I applied in my opinion every suggestions mentioned in VMware KB for our configuration including static arp etc. I can ping cluster virtual IP address from other networks. But IIS test site works only when called from the same network. Everything seems to be working when one of the two nodes is down. Then the test site is avaliable from other networks.
We have no idea why it does not work when two nodes are on-line.
Please help us to find solution of this problem.
Regards
Tomasz Krawczyk
