Office Communications Server becomes Microsoft Lync 2010

Recently Microsoft released some interesting  information about Office Communications Server. From now on, it is called Microsoft Lync 2010. Microsoft has also released a release candidate (RC) which can be found here:

Microsoft Lync Server 2010, Planning Tool Release Candidate (RC)

Microsoft Lync Server 2010 Release Candidate (RC)

For more information, have a look at this post on the Unified Communications Group Team Blog:

Integrate OCS 2007 R2 with Exchange Server 2010 SP1 OWA

I have seen a number of posts in different forums with questions on how to integrate Office Communications Server2007 R2 with Outlook Web App in Exchange Server 2010 Service Pack 1. There are some changes made in SP1 that will cause your current integration to break. But this can be easily fixed with a couple of configuration changes.

Changes? Why Changes??

Well, changes in this case is good. What Microsoft has done is to move the Instant Messaging settings for the OWA virtual directory from web.config to Active Directory where it should be. It’s better to have all parameters for OWA virtual directory gathered in one place, right?
Below, I will walk you through the complete configuration process. If you only want to read about the configuration related to SP1, scroll down a bit to configuration!


OCS 2007 R2 Web Service Provider found here:

Hotfix for the OCS 2007 R2 Web Service Provider:

Update Unified Communications Managed API 2.0 Redist (64 Bit) Hotfix KB 2282949:

When running Exchange2010 Sp1 on a Windows 2008 R2, include the following UCMAREDIST Update, available here:


The installation of the Web Service Provider is quite straight forward:
  1. Download and execute CWAOWASSPMain.msi to you Exchange Server 2010 CAS.
  2. In Windows Explorer, navigate to the directory where the files from CWAOWASSPMain.msi were placed. The default location is C:\Web Services Provider Installer Package\.
  3. Execute and install vcredist_x64.exe.
  4. Execute and install UcmaRedist.msi.
  5. Go to Start > All Programs > Accessories, right-click Command Prompt, and then click Run as Administrator.
  6. Go to the directory where the files from CWAOWASSPMain.msi were placed and run CWAOWASSP.msi.
  7. Install the other updates listed under pre-requirements above.
Done, you should now have all the required components installed on you Exchange Server 2010 CAS.


First we will configure the certificate. We start of by getting the thumbprint of the certificate by using the following command:
get-ExchangeCertificate | fl
Your thumbprint should look something like this:
To apply this to our configuration use the following command:
Set-OwaVirtualDirectory -Identity <"WebSiteIdentity"> –InstantMessagingCertificateThumbprint <CertificateThumbprint>
Set-OwaVirtualDirectory -Identity "SUNDIS-EX01\owa (Default Web Site)" -InstantMessagingCertificateThumbprint 4DC1EE3506E06E971FF82AC8DD60015EAC11B21E
Server Name
Next we set the server name for the OCS server, this should be the FQDN of the OCS server. Use the following command:
Set-OwaVirtualDirectory -Identity <"WebSiteIdentity"> –InstantMessagingServerName <ServerFQDN>
Set-OwaVirtualDirectory -Identity "SUNDIS-EX01\owa (Default Web Site)" -InstantMessagingServerName sundis-ocs01.sundis.local
Set type and Enable
Next we set the type of Instant Messaging Server to OCS by using this command:
Set-OwaVirtualDirectory -Identity "SUNDIS-EX01\owa (Default Web Site)" -InstantMessagingType OCS
And last but not least we enable Instant Messaging Server by using the following command:
Set-OwaVirtualDirectory -Identity "SUNDIS-EX01\owa (Default Web Site)" -InstantMessagingEnabled $true
Finish the configuration by doing a get to se the changes we made with the following command:

Get-OwaVirtualDirectory | fl InstantMessagingCertificatethumbprint, InstantMessagingServerName, InstantMessagingType, InstantMessagingEnabled

Well I almost forgot, the last thing you should do after all these configuration changes is to restart IIS by entering the following command:
iisreset /noforce
Now you should be all set!
OCS Settings
You do however need to make one last finishing touch on the Office Communications Server. That is to add the FQDN of the certificate that you specified in the Set-OwaVirtualDirectory command above as a trusted host in you OCS server. To do this Navigate to the pool or server in OCS, right click on your pool or server and select Properties and then Forest End Properties.ocsintegration5
Open the  Host Authorization tab and then click Add.ocsintegration6
Enter the FQDN found on the certificate you added in the previous step and make sure that you check Throttle AS Server and Treat As Authenticated, when finished click Ok. The FQDN will most certainly include a external domain in your case. In my case it’s an internal domain for testing purposes.ocsintegration7
Make sure that all settings are correct, when finished click Ok.ocsintegration8
Give OSC a moment to apply the settings and then head of to OWA and enjoy!
Thanks for reading and don’t hesitate to comment if you have any further questions or thoughts about the post!

OCS 2007 R2 – Deploy Server Wizard Has Failed

Recently I was doing an installation of OCS 2007 R2 Standard and I got this message when running the installation wizard:


In the log I found the following error message:

[0xC3EC796C] One or more errors occurred during execution of the wizard; the wizard was unable to complete successfully. Please check the log file for more information.


And when looking a bit further, following the link provided in the first message i found this error message:

[0xC3EC78D8] Failed to read the Office Communications Server version information. This can happen if the computer clock is not set to correct date and time.



According to Microsoft this can be related to Security Update for Microsoft Windows (KB974571). There are two things you can do to resolve this issue.

  1. Uninstall update KB974571.
  2. There is a fix available from Microsoft. Look under section “Resolution for these known issues” on the following link: http://support.microsoft.com/kb/974571/en-us

Windows Storage Server 2008 Default Password

I was installing Windows Storage Server 2008 this evening and where going crazy about the default password that Microsoft decided to add to this server. I dont really see the reason why they would set a default password since no other servers has one.

Anyways, here is the password: wSS2008!

Good luck!
