ESE function call (0xc7ff1004)

Whe you setup a new Exchange Server 2007 SP1 CCR on WIndows Server 2008 SP1 systems you may get the following error while updating a storage group copy from the EMC on the passive node:

Log Name: Application
Source: MSExchangeRepl
Event ID: 2015
Level: Error
General: Storage group ZEBDEMSMAIL00\09-Test failed to seed at E:\Mailboxes\09-Test. Reason: Error returned from an ESE function call (0xc7ff1004), error code (0x0)..

The problem is an EMC connection which is being blocked by the Windows Firewall. Powershell is beeing added to the Firewall's exclusion list, but EMC is not. If you configure the Windows Firewall to display a popup window when a blocked connection is detected, the following window pops up during the Update-StorageGroupCopy command:

Just unblock the connection and the command is being executed successfully.

Now move the cluster node to the second node and repeat the Update command on the passive node.
