Setting up CCR - There was a problem accessing the registry on this computer

Guys,

Recently, when we are setting up CCR for one of our customer, we got this weird message when Exchange 2007 is doing its Readiness check - There was a problem accessing the registry on this computer.

After hours of checking - its because of:
1) We disable File and Print sharing and
2) Client for Microsoft Network

For the heartbeat as this is the recommended way to setup a cluster.

Once we enable back those two, everything just flies...

Hope this will help some of those facing this problem.

SP1 to install in CCR

Recently, one of our customer is asking on how to implement Exchange 2007 SP1 into thier beloved CCR.

As known, CCR is a clustered solution, which means only can fit in Mailbox Server Role. Thus, to apply SP1, it is recommended to apply to a CAS (Client Access Server) and HUB (Hub transport Server) first.

Once both of the server updated, then you can update your CCR by using a command prompt, not GUI :)

Upgrade your CCR to a passive cluster node (eg: Node 2) first using the following command:

setup /m:upgrade

Once successfuly, upgrade the active node (eg: Node 1).

Installing Exchange 2007 SP1

Final release of Exchange 2007 SP1 few days back. Managed to successful deploy it in one of the production environment.

Something to share here - you will recommend to install patch for KB 942027 - an issue of .net framework 64bit performance tuning.

If you have antivirus that is bind to Exchange services and IIS, you will need to stop the service for the moment.

It will then take about 20 minutes to install (depending on the spec of your machine).

Few thing to share here. Its a total reinstall of Exchange binary files. So, it will as usual check the pre-requisite on the installation, remove Exchange existing binary then install the binary. You will need to have a moment of downtime, thus, plan out your maintenance window.

So, start roll it out and enjoy the benefit.

Standby Continuous Replication Steps

Thanks for drop by on my track session during OCS Launch 31 Oct. Some of you actually asking for the step on the SCR demo.

Here you go. To enable SCR, you will need to have:
1) Both source and target to be Exchange 2007 SP1
2) One store per storage group

Assumption:
Source Server Name: DC1
Target Server Name: W2K8-E2
Source SCR Storage Group Name: SG1, Store Name: SG1.edb
Target SCR Storage Group created SG1Port, Store Name:Mbx1Port

Steps:
For the source SCR,
# **** This is to enable SCR to SG1 ****
Enable-StorageGroupCopy SG1 -StandbyMachine W2k8-E2 -ReplayLagTime 0.0:0:0#
**** This is to check the SCR Status in W2008 ****
Get-StorageGroupCopyStatus SG1 -StandbyMachine W2k8-E2

For the target SCR,
# **** We will now go back to the production Server and Simulate Failure ****
# **** Now, time to Restore the enabled SCR ****
Restore-StorageGroupCopy DC1\SG1 -StandbyMachine W2k8-E2 -force:$true
# **** Now, we will move DB portability DB ****
Move-StorageGroupPath W2k8-E2\SG1PORT -SystemFolderPath C:\SG1 -LogFolderPath c:\SG1 -ConfigurationOnly -Confirm:$falseMove-databasepath W2k8-E2\SG1PORT\Mbx1Port -EdbfilePath C:\SG1\SG1.edb -ConfigurationOnly -Confirm:$false
# **** Allow the Database to be overwritten ****
Set-Mailboxdatabase W2k8-E2\SG1PORT\MBX1PORT -AllowFileRestore:$true
# **** Mount the Database ****
Mount-Database W2k8-E2\SG1PORT\Mbx1Port -Confirm:$false
# **** Update Mailbox configuration in AD to map to the DB portability copy ****
get-mailbox -database DC1\SG1\SG1 where {$_.objectClass -NotMatch '(SystemAttendantMailboxExOleDbSystemMailbox)'} Move-Mailbox -ConfigurationOnly -TargetDatabase W2k8-E2\SG1Port\Mbx1Port -Confirm:$false

There you go. You might want to put into a powershell script and rename it to .ps1

Happy SCRing
