Upgrading Exchange 2010 Beta to RC1

Requirements for upgrading Exchange 2010 Beta to RC1 on Windows Server 2008:

Software pre-req.:

• Windows Server 2008, Service Pack 2.
• Windows Remote Management (WinRM) 2.0 and Windows PowerShell V2

Configuration:

sc config NetTcpPortSharing start= auto

Upgrade Order:

1. Mailbox servers

2. CAS & Hub Servers

If you get this error opening Exchange Management Console:  ”Initialization Failed – The following error occured when getting role assignment information for <domain>\administrator: The role assignment method, User, isn’t recognized. It was running the command…” , then try removing Administrator account from Exchange Organiztion Administrators Group.  Ref.: http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/375cf88d-4879-4dc9-a522-bcbf6bedc1b0

How to run vSphere Host Update Utility on Windows 7 x64

Follow these instructions to fix vSphere client on Windows 7: http://communities.vmware.com/thread/211440

xcopy “C:\Program Files (x86)\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe.config”    ”C:\Program Files (x86)\VMware\Infrastructure\VIUpdate 4.0\VIUApp.exe.config”

Create bat file for VIUApp.exe:

 

SET DEVPATH=c:\Program Files (x86)\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib

“c:\Program Files (x86)\VMware\Infrastructure\VIUpdate 4.0\VIUApp.exe”  

SET DEVPATH=c:\Program Files (x86)\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib

“c:\Program Files (x86)\VMware\Infrastructure\VIUpdate 4.0\VIUApp.exe”

Without these changes, VIUApp.exe fails adding hosts with error “The type initializer for ‘VirtualInfrastructure.Utils.HttpWebRequestProxy’ threw an  exception.”

“Failed to set basic mailbox information, will retry in 60 seconds” in move-mailbox cross-org

When running Move-Mailbox in a cross-org scenario you get ”Failed to set basic mailbox information, will retry in 60 seconds” 

The cause seems to be that the Mailbox Server and Move-Mailbox cmdlets are using different DCs. So making sure that both use the same DC will fix this error

Using a specific DC (on destination forest), with -DomainConrtoller & -GlobalCatalog switches

get-mailbox -DomainController ‘dcA.src.local’ -Credential $s -database ‘Server1\DatabaseA’ | move-mailbox -TargetDatabase ‘Server2\Database1′ -Identity ‘testMailbox1′ -SourceForestGlobalCatalog ‘dcA.src.local’ -GlobalCatalog ‘dc1.dest.local’ -DomainController ‘dc1.dest.local’ -NTAccountOU ‘OU=UsersOU, DC=dest, DC=local’ -MaxThreads 8 -SourceMailboxCleanupOptions DeleteSourceNTAccount -SourceForestCredential $s -TargetForestCredential $t -ReportFile “C:\Logs\migrationReport.xml”

Excluding specific DCs for Mailbox server role to use with -StaticExcludedDomainController

Set-ExchangeServer -identity Server2.dest.local -StaticExcludedDomainControllers:dc2.dest.local,dc3.dest.local.

Assuming that on destination forest exist 3 dcs: dc1, dc2, and dc3.

Another workarround is leave only one DC up and running, so replication will not be involved.

Preserving ost files in a cross-org migration with Move-Mailbox

One of the most important features in an Exchange cross-org miration  is to preserve OST files. That is done by using “clone mode” on Exchange Migration Wizard  (mailmig.exe /m).

On Exchange 2007,  move-mailbox is the tool used to do Cross-org mgrations. Using -NTAccountOU parameter the “clone” operation is implicit. The -NTAccountOU option is mutually excusive with -AllowMerge option.

Inexpensive virtualization with VMWare ESXi

This is my recipe for an inexpensive lab with VMWare ESXi:

Enbale SSH access: use this procedure http://www.vm-help.com/esx/esx3i/ESXi_enable_SSH.php . Remember it’s not supported by VMWare, but who cares!

Install all your “base” VMs. Also known as templates

Clone VMs by copying vmdk files and using thin disk to preserve space; use this link http://www.virtually-challenged.com/?p=46

Extend your storage with openfiler. http://www.openfiler.com

How to install VMWare tools on openSuSE guest

zypper in gcc gcc-c++ make kernel-source

From the VI Client, opent the console VM, go to VM menu -> Install/Upgrade VMWare Tools

mount /dev/cdrom /media

rpm -Uvh /media/*.rpm

config-vmware-tools.pl

Export/Import mail-enabled contacts with ldifde

ADMT doesn’t support migration of contacts, so an alternative is to use ldifde to export and import contacts.

These are the main attributes needed to make the imported contact a mail-enabled one (At least for Exchange 2003)

cn,objectclass,samAccountName,legacyExchangeDN,

mail,mailNickname,proxyAddresses,displayName,targetAddress

And these are some general atributes that you may need to copy:

givenName,sn,name,physicalDeliveryOfficeName,description

Command line to export contacts:

ldifde -f file.ldf -s dc01 -d "ou=Contacts,dc=example,dc=com"
-p subtree -r "(&(objectCategory=person)(objectClass=Contact)(givenname=*))"
-l "cn,givenName,objectclass,samAccountName,mail,legacyExchangeDN,mailNickname,proxyAddresses,
physicalDeliveryOfficeName,displayName,name,description,sn,targetAddress"

Probably you are importing those contacts to a different domain/forest, so you need to replace the domain name (“dc=example,dc=com”) with the new one on the ldf file.

Command line to import contacts:

ldifde -i -f file.ldf


Downloading iso files with wget

For some reason every time I try to download iso of openSuSE I get the wrong file size (363431936 bytes). The solution is to add –ignore-length

wget -c http://download.opensuse.org/distribution/11.1/iso/openSUSE-11.1-DVD-x86_64.iso –ignore-length

Hyper-V Update List

First time you implement Hyper-V a question pop-ups, what are the hotfixes needed for Hyper-V? Besides KB950050 that is required to bring your Hyper-V to the RTM version, there are serveral updates that might apply to your environment. This url has the “live” list of updates:
