Internal certificates work wonders for your Active Directory Domain Services members. For Unified Communications, where OCS and Exchange are going to be using the same ISA 2006 server as the firewall, utilizing a Subject Alternative Name (SAN) certificate for your edge configuration and your ISA configuration can save you time, management hassles, and possibly provide cost savings as well. For internal servers, an internal PKI is just fine, but for the public interface of your system, you should most likely be looking at using a public-sourced key such as Go-Daddy, Thawte, DigiCert, etc. OCS Federation, remote users, and Public Instant Messaging Connectivity (PIC) demand public certificates.

The following table shows the SAN names needed on a certificate to support the base OCS and Exchange functions on ISA 2006 – and I imagine that this certificate construction will work just fine on many other firewalls as well. The table comes from my test domain; you should replace my test domain with your own domain name.

Obtain a public SAN (UCC) certificate from your favorite provider, import the certificate into your OCS Edge server and your ISA server computer account Trusted Root Certificate store and then you can use one certificate for all these uses. This approach leaves you with only the one certificate to manage and renew, or, if life treats you badly, move to a new server.

Multilingual User Interface Package for Microsoft Office Communicator 2007 R2

Posted by Mino on April 26, 2009

I have been into a deployment within the GULF countries where the language of the application is much more important than the application itself.

English is not commonly used and the localized language was requested even on the OCS level.

Microsoft Provides localized MUI (Multilingual User Interface ) for Both Communicator Client 2007 R2 and Communicator Web Access. However there is no MUI yet for the Communicator Phone Edition 😦

This MUI Package for Office Communicator 2007 R2 includes the following languages:

·         Arabic

·         Bulgarian

·         Catalan

·         Chinese – Simplified

·         Chinese – Traditional
