There are some users that are experiencing errors on CCR (cluster continuous replication) passive nodes or SCR (standby continuous replication) target machines. 

Here is an example error:

Event ID     : 522
Raw Event ID : 522
Record Nr.   : 3965
Category     : General
Source       : ESE
Type         : Error

Message      : Microsoft.Exchange.Cluster.ReplayService (7012) Log Verifier e0a 31573001: An attempt to open the device name "\\source\share$" containing "\\source\share$\" failed with system error 5 (0x00000005): "Access is denied. ".  The operation will fail with error -1032 (0xfffffbf8).

The error -1032 (0xfffffbf8) translates to Jet_errFileAccessDenied.

The errors most commonly occur when:

1)  Replication is paused and resumed automatically to accomidate a backup operation.

2)  Replication is paused and resumed using suspend-storagegroupcopy and resume-storagegroupcopy (or through the GUI equivalents in the Exchange Management Console).

3)  The replication service is restarted or the entire node / target is restarted.

4)  Databases are mounted and dismounted using dismount-mailboxdatabase and mount-mailboxdatabase (or though the GUI equivalents in Exchange Management Console).

5)  The CMS (clustered mailbox server) is stopped and restarted using stop-clusteredmailboxserver and start-clusteredmailboxserver (or though the GUI equivalents in Exchange Management Console).

If you manually review the log file directories on the passive or target machines they are relatively in sync with the source machine. 

Likewise, when using any replication health check including get-storagegroupcopystatus, get-storagegroupcopystatus -standbymachine, and test-replicationhealth no errors are displayed.

Here is an example get-storagegroupcopystatus on a two node Exchange 2007 SP1 / Windows 2008 CCR cluster.

Here is an example of test-replicationHealth

The error is caused by an invalid function call from the replication service to the operating system.  This causes the operating system to respond with access denied, and the replication service to respond by logging the ESE 522 event.

This issue is scheduled to be corrected in Exchange 2007 SP1 RU7.  There is currently no incremental update for the issue.

The issue can be considered benign if:

1)  Visual inspection of the log file directories show that replication is occurring.

2)  Get-storagegroupcopystatus or get-storagegroupcopystatus -standbymachine shows all storage groups in healthy state (some storage groups may be in an initializing state, in which case logs will need to be generated to determine status).

3)  Test-replicationhealth when run on the passive node or target server shows all tests passed.
