Just like in OCS with Lync you can add distribution lists to your contact list.  However, there is a default limitation on how many groups you can add to your list.  In Lync and OCS that limit is 10, which … Continue reading

Welcome to Lync!

It’s official; the new name of OCS is Lync! With the name change comes a number of new features including revamped management interfaces (Topology Builder, Deployment Wizard and CSCP) and a Management Shell with tons of great new scripting capabilities.

With all of these new features available, and a new way to deploy I thought it would be fitting to cover deploying a topology. To start things off easy we’ll jump into a single box Standard Edition pool. Over the next few articles I will add layers to this deployment until it resembles what you may want to use in your environment.

Keep in mind the RC is for lab use only; it is not a good idea to install this into your production domain. Also, please read the reference documents here:

Now let’s start with a link to the download:

For this install you’ll need a DC/DNS/CA server (I named mine lyncdc.ocsguy.local), we’ll bypass that portion of the install to keep the article to a reasonable length.

Once you have your Lync Server on the domain we need to install all the pre-requisites:

Here’s a quick ServerManagerCMD script to make that happen, to use this on the Start menu,to use this open a Command Prompt (Run As Administrator) and paste the information below. For formatting purposes copy this into notepad and make sure when wordwrap is unchecked it is all on one line.

OCS Reverse Proxy from Forefront TMG on a UAG Server – Getting Some Bang For Your Buck

As you may have guessed by the title, I get paid by the acronym….

With the release of Microsoft’s Forefront Unified Access Gateway (UAG) many companies have found a very useful product to securely publish applications such as OWA, Direct Access and SharePoint (among many, many others) from one place. UAG also includes a TMG server built into it, which you can utilize as a reverse proxy for OCS or other applications you don’t want to require authentication for. Microsoft even has a great support article detailing what is and isn’t supported here. The article very clearly states you can utilize the TMG on your UAG server to publish OCS (although it doesn’t specify which roles); however making it all work is not as intuitive as one might hope. With that in mind, I’d like to share what I learned while working on a recent deployment to help others who want to utilize their UAG for other purposes.

For starters let’s talk about the network; here is what my lab looks like for this scenario…..

Citrix NetScaler VPX and OCS 2007 R2 – Certificates

In the past few months it’s been a bit quiet on the posting front. The major reason being Wave 14 (CS2010) is taking up a lot of my time and there isn’t a lot we’re allowed to show from our labs yet. As the end of the year approaches, the public beta’s and/or release candidates hit the net, and the RTM comes out you can expect a lot more information from all of the UC bloggers, but for now we’ll stick with OCS 2007 R2.

My current lab is an OCS 2007 R2 environment with 2 Front End servers and a Citrix NetScaler virtual appliance (VPX) running as a load balancer. I’m prepping the environment to simulate a migration from R2 to Wave 14 utilizing the document here (this is an RTM version, but it gives you the jist). But as is usually the case, I found a gotcha on the certificate setup on the VPX, and thought it was worth sharing. This particular gotcha even had the citrix support folks scratching their head….
