OCS 2007 R2 (Server Side) - January 2010 Updates

Not a lot of changes, server side for OCS 2007 R2 in these updates but a few that have been longstanding annoyances. On a plus note, these updates remove the need for applying the OCS ASN fix caused by KB 974571 (MS09-056).

For the overall list of server updates and update guidance, check out KB 968802.

If you look over the list at the KB article above, you'll notice that only certain components were updated for January 2010:

Administration Tools (AdminTools.msp) and Core Components (Ocscore.msp):

KB 978371 - An offline certificate request is formatted incorrectly when you create the certificate request in Office Communications Server 2007 R2 on a computer that is running Windows Server 2008

This fix is particularly welcome because the certificate request output varied depending on if the server used Server 2003 or Server 2008. Some certificate authorities require -----BEGIN CERTIFICATE REQUEST----- at the beginning of the certificate request and -----END CERTIFICATE REQUEST----- at the end.

Server (Server.msp):

KB 978363 - You experience performance issues in Office Communications Server 2007 R2 during NTLM authentication

KB 978364 - You experience performance issues in Office Communications Server 2007 R2 when you move many users between pools at the same time

KB 978366 - Instant messages are blocked in Office Communications Server 2007 R2 if a third-party application uses the "otherIpPhone" attribute

KB 978367 - You cannot start the Office Communications Server 2007 R2 Front-End service if the connection to the root domain controller is lost

KB 978369 - Instant messaging fails when the Office Communications Server 2007 R2 front-end server that you connect to changes

Database (OCS2007-DBUpgrade.msi):

Not installed by ServerUpdateInstaller.exe - must be installed manually with all the other updates if you want proper operation.

The link to the Download Center seems invalid at the moment but the Request Hotfix link works.

KB 978362 - You experience performance issues in Office Communications Server 2007 R2 when many legacy presence users are converted to enhanced presence users at the same time

Unified Communications Managed API 2.0 Core Redist 64-bit:

KB 978372 - CPU usage increases when you turn on tracing for the S4 component in Office Communications Server 2007 R2

As always, the easiest method of installing the updates is to use the ServerUpdateInstaller.exe, combined with the manual application of the database update.
