Updates for Communications Server 2007 R2 (almost SP1!)

Microsoft has released a set of 13 patches for OCS 2007 R2. You might think of this as SP1 for OCS 2007 R2 (but that’s not the say MS is marketing it). Irrespective of what they call it, this set of patches is probably worth adding if you are deploying R2. As ever with patches, check the details to see if your systems are affected by each of these patches and which ones.

Due to the complex nature of OCS Deployments, patching is hard as there’s not just a single patch you can apply to all systems – you have to apply some patches on some systems and other patches on other systems. For example, an OCS 2007 R2 SE system needs 9 patches, while the Edge Server needs three. So plan this carefully as, at the least, you’ll need some service outages to apply the fixes.

The KB article: List of available updates for Communications Server 2007 R2: April 2, 2009, lists all 13 patches and describes which patch needs to be installed on which server role. You can drill down into each of the 13 individual patches – each has its own KB article. Most of these KB articles explain the issues resolved by the patch. KB 967675 that describes the fix to the Mediation server does not contain details of the fixes, but that’s probably just a doc error that will get fixed soon. For each individual issue, there’s a link to (another!) KB article describing the specific issue in more detail which include the symptoms of the (resolved) issue.

All in all, this is a useful update and well packaged. Next time though, couldn’t we have a mondo-patch (R2PatchAug09.exe for example) that you must apply to every related OCS system. That would help with the deployment and could reduce support calls especially from organisations deploying distributed Enterprise pools.
