I want to create NLB cluster of two Exchange 2007 servers with roles CAS and
HUB Trunsport on both. This is needed for failover of OWA and SMTP access of
internal servers and services.
I have a problems on a step of assembling NLB.
I have created an intercluster network interface on both servers with
dedicated (separate) subnet.
After that I create an NLB on other (public) network adapter of first node.
After creating appears an error that interface must have second IP address
same as virtual cluster IP. After I add second IP in TCP settings of public
interface, server goes to reboot with unexpected error. After reboot Exchange
looses connection with DNS and AD (I have checked, DNS servers and DCs
recalls on ping).
Error is:
No DNS servers could be retrieved from network adapter
00000000-0000-0000-0000-000000000000. Verify that the computer is connected
to a network and that the Get-NetworkConnectionInfo cmdlet returns results.
As a result Exchange does not work. What am I doing wrong?
