Symantec Backup Exec 2010 R2 with hotfix 143746 installed & Exchange 2003 GRT backups

Posted by bartvdw on 2121/0101/2011

Some time ago backups started failing for Microsoft Exchange 2003 server, GRT option enabled using Symantec Backup Exec 2010 R2. The error message was "Cannot log on to MAPI with the specified credentials.". This error message pointed me in direction that there was an issue with the credentials, however the backups have ran always without any problem and no change was executed in this direction.

The original setup for this backup was first to disk, then duplicate to tape. During my investigation I changed the job to use tape directly as test. This caused the error message to change: "Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: ‘-528 The current log file is missing. ‘".

This finally has lead me to a KB from Symantec that this is caused by hotfix 143746 for Backup Exec 2010 R2.

Disabled Advanced Open File Option, job runs fine again.

Antivirus software exclusions

Posted by bartvdw on 1313/0808/2008

When you configure antivirus software for servers, you need to take exclusions into account. And for MS products, they are fairly good documented. If you don’t add these exclusions, you could get trouble/errors. For applications not listed here (MS or third party), always verify if you need to exclude something to make sure your antivirus software does not affect your application!

Below a summary of such exclusions and references to MS articles describing these exclusions. I will update this post in case I have additional information.

Note: In the list below, default file locations are used. If you have change the location of the files (ex. Ntds.dit), you need to use the altered path obviously!!

General exclusions Windows Server 2003, Windows 2000, Windows XP, or Windows Vista:

  • %windir%\ntfrs
  • %windir%\SoftwareDistribution\Datastore\Datastore.edb

  • %windir%\SoftwareDistribution\Datastore\Logs\Res2.log
  • %windir%\SoftwareDistribution\Datastore\Logs\Edb.chk
  • %windir%\SoftwareDistribution\Datastore\Logs\Tmp.edb
  • For Windows 2000 & 2003 DC’s

Outlook and Global Catalog…

Posted by bartvdw on 1313/0808/2008

A collegue of mine was recently working on a Citrix server in a remote site and noticed that starting Outlook was really slow. Setup:

– Main data center: DC’s + Exchange
– Remote site: DC + Citrix servers

When he checked, he noticed a lot of traffic going to the DC’s in the main data center and not to the local DC although the local DC was also GC. When he checked he found that Outlook connects by default to the same GC as the Exchange server. A quick search revealed that there is a registry tweak to have Outlook connecting to the nearest or specific GC. See the MS KB for details! After setting that registry entry, Outlook opened in just seconds i.o. minutes!!


Connect to the nearest GC

HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider

Value name: Closest GC
Data type: REG_DWORD
Radix: Hexadecimal
Value data: 0x00000001


Connect to a specific GC

HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider

Value name: DS Server
Data type: REG_SZ (string)
Value data: FQDN of the global catalog server
