Restore email from Exchnge 2013 Dag clustering using RDB recover

I have Exchange 2013 sp2 Dag clustering (2x Exchange CAS and 2X Exchange database servers)

Networker client 8.1.1.5 build.306 and NMM 3.0.1.2.298  is installed on First Dag server!

Before dag clustering restore with RDB was successful. After DAG clustering when I try to restore

Mails with RDB database I was prompted with user and password. No matter what user and password I enter nothing was accepted and RDB restore was unsuccessful.

Searched all over forums no one had a problem like that. Opened a case with support. Did everything they asked, sent a ton of logs, nothing, no solution.

So I was on my own. Then started to search how mails are actually restored from RDB database.

Networker used a clever solution. Mount RDB database and use MAPI connection to search and open

emails. Ok , great then. Find Microsoft MAPI tool (mfcmapi.exe) and try to connect to RDB database.

With that tool I have find out that networker creates MAPI profile „Legato NetWorker“ and when I try to connect with that profile I am prompted with same user and password like I was trying RDB restore. Bingo one step closer. Then I took me a lot of searching why it won't connect to RDB database. Ended up creating profile that worked and compare that with one created with networker. I used this web for reference with creating profile. http://blogs.msdn.com/b/dvespa/archive/2013/05/21/how-to-mfcmapi-create-mapi-profile-exchange-2013.aspx

When I have compared profiles this was the difference:

RPC_C_HTTP_AUTHN_SCHEME_BASIC – profile created with networker

RPC_C_HTTP_AUTHN_SCHEME_NTLM – profile created by hand

So it was the authentication issue. In my exchange setup „Basic „authentication is disabled only „NTLM“is allowed.

Then it took me a lot of time to find the last piece of the puzzle.

If i change the „legato“ MAPI profile from basic to Ntlm and start RDB recover networker automatically restores the „basic“ authentication.

So it had to be hard coded or registry key to change that...

I started to search registry and luckily found it!

HKEY_LOCAL_MACHINE\SOFTWARE\Legato\NetWorker\RecoverOptions\MapiProfile

External AuthPackage = Basic -> Change it to „Ntlm“and RDB restore was successful!!!

Sorry for the long post but it took 3 months to resolve this issue.

Also, big thanks for support and installing numerous versions with no success at all…
