Troubleshooting: Why NB70 can't backup Exchange 2010 DAG on Windows 2008 R2?

Hi experts,


I am in such scenario:
I have three Window Serve Enterprise 2008 R2:
VMExchange : 10.200.108.10, only install Exchange 2010 Hub Transport role and as the witness server for dag01No NBU installed.
08r2chs-16   : 10.200.123.16, install Exchange 2010 with default roles, have one default database, "Mailbox Database 1485122442". NBU 70 all-in-one installation.
08r2chs-26    : 10.200.123.26, install Exchange 2010 with default roles, have one default database. "Mailbox Database 1461955747". NBU 70 Client installed.

Every box only have a NIC (Microsoft said "Although using a single network interface card (NIC) is supported, we recommend that each DAG member have at least two NICs. " at <Managing High Availability and Site Resilience>), and they connect to each other with a router.
GW1: 10.200.108.1  for VMExchange
GW2: 10.200.123.1  for 08r2chs-16 , 08r2chs-26 .

The dag01 created successfully with 08r2chs-16 and 08r2chs-26 as members, VMExchange is the witness server.
Now here comes my questions:

1. I new a policy: Passive copy if active copy is not valide; local VSS with default settings; Enable granular restore; Client is 08r2chs-16, backup selectoin is the DAG directive.
But the backup job said:
no database with active server found in bpresolver log.
Job details said: bpbrm no worklist items returned from bpresolver on client exch02

I checked all my mailbox databases on 08r2chs-16 and 08r2chs-26 both, each database were mounted.

Could someone tell me why ? 
Please point it out for me ~~


FYI: Before I created the DAG, Exchange 2010 standalone env on  08r2chs-16 and 08r2chs-26 works well.

Thank you very much ~~

For my configuration:
I input the administrator@mydomaincom to Client Propertise.
I also setup a preferred list for DAG servers, they are 08r2chs-16 and 08r2chs-26.
There are some mails in my test email account; I use domain's administrator as NBU Client service runner;
But I didn't install MAPI. I thought Exchange 2007 need it, shall I ?

It happens because probaly you choose phisical names of servers in clients tabs. You should choose virtual name of cluster DAG.
