Hello,

We have 2 Exchange 2013 (build 712) servers in a DAG with distinct subnets. Cisco ASA in between was set to have no filtering between servers in subnet.

We cannot add database copies nor move mailboxes.

Tes-Mapiconnectivty fails with

Adding database copy fails with

The seeding operation failed. Error: An error occurred while performing the seed operation. Error: Failed to open a log truncation context to source server 'CLI-SRV02.CLI.ch'. Hresult: 0xc7ff07d7. Error: Failed to open a log truncation context because the Microsoft Exchange Information Store service is not running. [Database: CLI-PFDB02, Server: CLI-SRV01.CLI.ch]

How can I further verify communication from CLI-SRV02 to CLI-SRV01 ?

Any help w

I think you have verified that you are having communication problems.

I agree.

How can I possibly prove it to the Cisco FW admin?

Show him the error message?

Hi,

Let's begin with the following similar thread:
http://social.technet.microsoft.com/Forums/en-US/b651d65c-92f3-460c-b555-247acb8e6fd7/recovered-exchange-2013-arbitration-system-mailboxes?forum=exchangesvravailabilityandisasterrecovery
It is the same error in the event log with you when moving mailboxes. And it can be resolved by recreating the mailboxes.

Additionally, to check the network connection between two servers, I recommend you use the network monitor to catch the package.
Thanks

Hi Angela,

thanks for the hint but I'm afraid thread isw not applicable for my case. I have no problem with databases nor with arbitration mailboxes relocation.

There's a general mapi connectivity issue between the two servers despite

- TCP 135 being reachable both ways
- Netmon log showing multiple TCP & MSRPC conversations between servers while test-mapiconnectivity is ran; no trace of retransmit attempts
- Local Test-MapiConnectivity reports no problem
- Cisco ASA in between has no filter set between those two servers (reported from Network Admin)

FYI I opened a case at MPS and expecting a session in 2h.

Regards

Hi,

How about the issue now after you open a case at MPS? If you have any question, please feel free to let me know.

Did you ever get a response to this? 

I am having the same problem and have had a case open with MS for nearly 3 weeks to no avail...

To simplify it you can lock down the MAPI ports to two, then you'll know what ports to look at after the endpoint mapper (TCP 135) assigns a port.
