Problem
Event ID 8390 appears in the Veritas Enterprise Vault (EV) event log with the matching Event Task Category and Description. The solutions vary with applicable permissions or configuration issues that need to be addressed and resolved. Please be sure to check the specific error conditions using the Event Category as well as the Event Description to find the solution that is associated with the applicable case.
Error Message
Event ID: 8390
Event Category: Archive Task
Event Description: The EnterpriseVault.DirectoryConnection object reported an error. The RPC server is unavailable.
V-437-8390

V-437-6281
Event ID: 2776
Event Category: Archive Task
Description: An exception occurred in routine CArchivingAgent::GetDeletedItemFoldersList
V-437-2776
Solution
Scenario 1: Move Archive fails
Scenario 2: "Delete Orphan Shortcuts" enabled report mode produces errors
Scenario 3: Shortcut processing portion of archive task generates errors
Scenario 1:
Move Archive fails while searching archives in the destination Directory
Additional Information:
The issue occurs when an EV server in source or destination is unable to resolve the NetBIOS or FQDN of the other. You will see either one or both of these messages:
“failed to read the list of archives in the destination site”.
“failed to get the list of vault store, reason : RPC server is unavailable, check the vault directory is running and computer is reachable on the network”.
Dtrace Information:
To validate if this is the issue a DTRACE is needed, please perform the following steps on the EV server with the issue. For more information about Veritas Enterprise Vault’s Dtrace Utility please see
How to run Dtrace.
· Dtrace the service MMC for no less than 5 minutes while re-creating the issue.
· Open the log file created and search for either of the following the strings.
986 12:05:04.867 [5936] (mmc) <4536> EV:H CBaseDirectoryServiceWrapper::GetInterface - HRXEX fn trace : Error 0x800706ba ref[1]: EVSITE, .\DirectoryServiceWrapper.cpp [lines {653,693,719}], built Nov 24 00:04:09 2010.
989 12:05:04.867 [5936] (mmc) <4536> EV:M CAUIMoveArchivesSelectPage::GetMatchingArchive: Caught COM error The RPC server is unavailable.
Solution:
To correct this issue an update is needed in the host file to allow the host and destination servers a routing path to each other.
1. Edit host file and put all the IP with NetBIOS & FQDN of EV servers like below.
a.
On the applicable server navigate to
%windir%\system32\drivers\etc\hosts
<IP Address> <EVSite alias NetBIOS name>
<IP Address> <EVSite FQDN>
<IP Address> <EV server NetBIOS>
<IP Address> <EV server FQDN>
2. Flush DNS resolver cache (IPconfig /flushdns) on each EV server and restart EV admin service.
With "Delete Orphan Shortcuts" enabled, running the Mailbox Archiving Task in Report mode produces errors.
Additional Information:
In this scenario, ID 8390, 6281 and 2776 will display event viewer during an Archive Task run in Report Mode. This can occur for multiple reasons illustrated below.
Solution:
Each of the items listed below could generate the above Event ID messages. In an attempt to correct these messages, a comprehensive check will have to be performed in the environment. The steps listed below will help the investigation. Perform one action at a time
1. Check that both EV Directory Service and the Mailbox Archiving Task are running at the time the event occurs
2. Ensure that the Vault Service Account (VSA) is not part of the Domain Administrators group, but listed as a Local Administrator.
a. For more information about the correct configuration of the VSA, see the ‘Installing and Configuring’ Guide for your version of Enterprise Vault.
b. If any changes are made to the permissions of the EV VSA, restart all the EV services.
3. Verify these items between the EV Server and SQL Server
a. The Remote Procedure Call (RPC) service started
b. There is no network issue in the environment
c. There are no filters on the communication between the EV, Exchange and SQL Servers.
4. Review the environment for recent changes that have been made to the Group Policy or Active Directory
5. Check for old shortcuts in the users' mailboxes that references old EV Server / EV Site references
6. If none of options correct the issue it is safe to remove the 'Delete orphan Shortcuts' check option as you will only see this when running the task in report mode.
Event Viewer indicates multiple 8390 errors generated from the archive task. The issue occurs when it reaches the shortcut processing portion of task.
Additional Information:
This can occur during the moved shortcut update phase of the archiving task in EV 8.0 and later, if some users have shortcuts in their mailbox that belong to a foreign EV Directory. In some cases this will be expected behavior, here are some examples of when this scenario that can be ignored:
· Shortcuts were created during a pilot installation and were not removed from the mailbox.
· Shortcuts were created prior to a company merger.
· Shortcuts were moved into a PST and then imported into a mailbox serviced by a different EV Directory.
· The process recognizes the item as an EV shortcut and tries to determine whether it has been moved. It attempts to contact the Directory Service computer that is embedded in the shortcut, but that server no longer exists or is unreachable, and it logs an 8390 event.
Note: In this case, the error can safely be ignored, as it represents the failure of something that is not supposed to work in the first place.
To validate if this is the issue a DTRACE is needed, please perform the following steps on the EV server with the issue.
· For more information about Veritas Enterprise Vault’s Dtrace Utility please see
How to run Dtrace.
· Dtrace the service ArchiveTask for no less than 5 minutes while re-creating the issue
· Open the log file created and search for either of the following the strings:
(ArchiveTask) <4940> EV:H VaultCoCreateInstanceEx: An error occurred - RequestedServerName = [BOGUSSERVER.DOMAIN.COM], UsedServerName = [BOGUSSERVER.DOMAIN.COM], hrCCI = [0x800706BA], hrResultsQI = [0x80004005], NumTried = [6], bLocalMachine = [False]
(ArchiveTask) <4940> EV:M CBaseDirectoryServiceWrapper::CreateDirectoryService() failed.|Hr: 0x800706ba|Retries: 6|TryLocal: false|Directory Name: BOGUSSERVER.DOMAIN.COM|
Solution:
1. Avoid the moved shortcut update phase for the affected archive. This can be adjusted by disabling the updating of moved items in the archive task:
a. On the
Exchange Mailbox Archiving Task update the policy in the
Moved Items tab to disable
update archive location for items moved in the mailbox.
b. Perform a
Synchronization on each
Exchange Mailbox Archiving Task across all mailboxes
2. Set a bogus DNS:
a. The 8390 errors represent the failure to connect a Directory Service on the server.
b. Even if the shortcuts are not accessible in the current EV environment a change can be made in DNS that will allow a connection to the applicable Directory Service.
c. Make a DNS alias that points all traffic for BOGUSSERVER.DOMAIN.COM to the current EV server
d. Even though it will not be able to process the shortcuts, at least a Directory Service will answer and you should avoid 8390 in the Event Viewer.
