July Cumulative Updates for Communications Server 2007 R2

26 July 2010

The July updates have been released and can be downloaded from here.

For details of what is included in the patches can be found here http://support.microsoft.com/?kbid=968802 along with installation details.

A few people have mentioned issues with the latest update but this appears to be because the OCS2009 DBUpgrade hasn’t been applied. This needs to be applied separately for a good description of how to apply this patch there are a number of blog entries such as the one on msunified.

Update 30 July

I left off the other updates below when I initially posted this

Exchange 2007 Certificate Manager

10 June 2010

I still find that customers are using self signed certificates for their Exchange servers. When you install Exchange UM and want to link it to OCS you need to use a properly trusted certificate from a CA. To do this requires some messing around in Powershell and can be inconvenient. Today I spotted a blog post from Rui Silva highlighting a Certificate Management Tool from U-BTech which gives a quick and easy GUI to manage the Exchange server certificates. I haven’t tried it yet but I think it is definitely worth investigating.

Microsoft OCS 2007 R2 Workload Poster

25 January 2010

Microsot have recently released a Workload Architecture poster showing protocol flow, ports, DNS and Certificates. It gives a graphical representation of information found in the various OCS manuals all in one place.

This poster only shows the IM & Presence, Conferencing, Application Sharing and Enterprise Voice Worloads. However it does show everything for internal and also external access through an Edge Server.
