MVP Summit 2009 & I’m a PC

April 2, 2009 at 11:56 AMSaso Erdeljanov


I was attending Microsoft MVP Summit 2009 in Seattle at the beginning of March. It was nice meeting all great people from around the world! I would like to thanks to Microsoft for organizing such a great event with 700 sessions, EMP party, breakfast and lunch, hotels were covered,…

I must say that Exchange team is really great! I enjoyed talking with every member of Exchange team that I meet.

During Steve Balmer’s keynote we were part of I’m a PC campaign. For sure it was fun. :) Video is available from Microsoft home page.

POW #7 - DPM 2007 SP1 Error 0x80004002

January 5, 2009 at 11:30 PMSaso Erdeljanov


After updating my Microsoft System Center Data Protection Manager 2007 (DPM 2007) to Service Pack 1 (SP1) I received a bunch of errors regarding inconsistency and recovery points creation.





I was looking trough MSDPMCurr.errlog (located in C:\Program Files\Microsoft DPM\DPM) and found following error:

GetDifferentialSoftwareSnapshotMgmt3Interface () failed: (0x80004002)


It appears that Service Pack 1 does not correctly register VSS writer...

After searching around I found solution on Ask The Core Team blog. You need to re-register vss_ps.dll on server.


  • Run cmd.exe (with administrative privileges in Windows Server 2008)
  • Run regsvr32 %windir%\System32\vss_ps.dll
  • Restart Volume Shadow Copy service

POW #6 - Exchange Server 2007 SP1 & IPv6

December 23, 2008 at 11:35 AMSaso Erdeljanov


As we know from previous post Service Pack 1 for Exchange Server 2007 brings support for IPv6 but only in combination with Windows Server 2008 and IPv4.


But there were some known issues with IPv6. For example:

  • Outlook Anywhere connectivity issue (DSProxy ::1:6004) - KB950138

Issue mentioned above was most annoying since you received login screen multiple times and was still unable to connect. This issue was already fixed and update is included in Update Rollup 4 for Exchange Server 2007 SP1. Update Rollup 5 for Exchange Server 2007 SP1 is the latest version at the moment and I recommend you strongly to apply it.

IPv6 recommendation

There is only one simple rule. Disable IPv6 if you do not need it!

Disabling IPv6

  • Uncheck Internet Protocol Version 6 (TCP/IPv6) on network card.
  • The above step is not enough! Remove or comment out the line ::1     localhost in HOSTS file.

  • Disable IPv6 in registry.

    DWORD: DisabledComponents
    Value: 0xFFFFFFFF


That's it. :)


Merry Christmas and a Happy New Year!


I  wish you all Merry Christmas and a Happy New Year! Here are some free e-books for cold days... :)

POW #5 - Windows Server 2008 & Exchange Server 2007 SP1

December 5, 2008 at 1:42 PMSaso Erdeljanov


I guess many of you have already heard phrase "Windows Server 2008 & Exchange Server 2007 SP1: Better Together"? :) In general this is true but there are some gotchas!

  • Support for multi-subnet failover clusters
  • Better performance of file copy operations (SMBv2)
  • Reduced downtime for hardware maintenance (Hot add, remove, replace of core hardware components)
  • Reduced downtime for fixing NTFS issues (Self-Healing NTFS)
  • Greater scalability of TCP/IP connections (Client Access Server especially; Next Generation TCP/IP Stack)
  • Integrated Exchange Server 2007 prerequisites (PowerShell,...)
  • IPv6 support (only in combination with Windows Server 2008 and IPv4)
Installing Exchange Server 2007 prerequisites

The easiest way to install all prerequisites on windows Server 2008 is with ServerManagerCmd command line utility.

Exchange Management Tools

ServerManagerCmd -i PowerShell

If you want to manage all internal server roles including CAS role you must also install following IIS components. Note that this also applies if you have stand alone HUB Transport server and you want to manage CAS server from it.

ServerManagerCmd -i Web-Metabase
ServerManagerCmd -i Web-Lgcy-Mgmt-Console

Hub Transport Server

ServerManagerCmd -i PowerShell

Edge Transport Server

ServerManagerCmd -i PowerShell
ServerManagerCmd -i ADLDS (AD LDS - Active Directory Lightweight Directory Services; previously known as ADAM - Active Directory Application Mode)

Mailbox Server

ServerManagerCmd -i PowerShell
ServerManagerCmd -i Web-Server
ServerManagerCmd -i Web-ISAPI-Ext
ServerManagerCmd -i Web-Metabase
ServerManagerCmd -i Web-Lgcy-Mgmt-Console
ServerManagerCmd -i Web-Basic-Auth
ServerManagerCmd -i Web-Windows-Auth
ServerManagerCmd -i Failover-Clustering (if Mailbox Server will be clustered)

Client Access Server

You don't need a separate command for every component. Instead you can write every component you need separated with space.

ServerManagerCmd -i PowerShell Web-Server Web-ISAPI-Ext Web-Metabase Web-Lgcy-Mgmt-Console Web-Basic-Auth Web-Digest-Auth Web-Windows-Auth Web-Dyn-Compression RPC-over-HTTP-proxy

Unified Messaging

ServerManagerCmd -i PowerShell
ServerManagerCmd -i Desktop-Experience (audio/video codecs required by UM)

Exchange Server 2007 SP1 Update Rollup 5

Update Rollup 5 resolves some important issues in combination Windows 2008/Exchange 2007.

Here are some of more important updates:

  • Exchange 2007 CAS cannot copy the OAB from the OAB share on Windows Server 2008-based Exchange 2007 CCR clusters (KB954197)
  • The OAB generation is unsuccessful and Event IDs 9328 and 9373 are logged in the Application log in a Windows Server 2008-based Exchange 2007 Single-Copy cluster environment (KB957978)
  • Exchange Server 2007 Update Rollup 3 does not update the Outlook Web Access Logon.aspx file after you modify the file (KB956582)

Complete list of included updates: Description of Update Rollup 5 for Exchange Server 2007 Service Pack 1 (KB953467).


The Christmas Wish!

At the moment there is no build in exchange-aware backup solution in Windows Server 2008. We are still waiting for VSS-based plug-in for Windows Server Backup! Ultimate (and cheap) backup solution at the moment is of course Microsoft System Center Data Protection Manager!


Well... it's not from me but anyway... :) Here is a free copy of Windows PowerShell Workbook: Server Administration!
