I released a small free troubleshooting tool back in October 2008 to help diagnose Communicator automatic sign-in issues. It queries all the possible DNS records that Communicator could use to connect to the OCS server, and displays all the associated matches on the client computer.
I have made some significant improvements based on feedback and rolled [...]
Being familiar with these 6 items before introducing an OCS R2 pool into an OCS deployment (with an existing OCS 2007 R1 pool) could save you some valuable time and frustration.
An important updated tip (tip #6 – a bonus), if you have Blackberry users, consider keeping an OCS 2007 R1 CWA server so that they are [...]
In light of the new OCS R2 server roles and capabilities, here is a summary of the significant changes on the server side and topology (from OCS 2007).

One of the goals of this blog is provide answers to important questions or issues that the public documentation does not clearly address. I recently encountered such an issue while trying to definitively determine the best OCS pool type in a relatively small deployment (about ~3500 users): Consolidated or Expanded.
The basic differences between Consolidated and [...]

When you look at the Certificate details, the Subject Name [...]
