Skype4B In-place Upgrade and LRS Admin Portal

May 11, 2015 1 comment

While reading through the In-place Upgrade docs, I spied this little nugget:

Be sure to uninstall LRS Admin tool for Lync Server 2013 before running In-Place Upgrade. The LRS Admin Tool for Lync Server 2013 cannot coexist with Skype for Business Server 2015. After running In-Place Upgrade install the new LRS Admin tool, see Microsoft Lync Room System Administrative Web Portal for Skype for Business Server 2015

I haven’t tested this but the fact that they say to Uninstall the Lync Server 2013 LRS Admin Portal was the big catch. Make sure you read all of the docs a few times before you start the upgrade process.

Lync Edge Server Port Ranges and QoS

March 30, 2015 4 comments

Ran into this and felt like until the documentation is updated, I should call this out.  On this Technet article, it shows you how to configure port ranges for Edge Servers in Lync Server 2013. In the hopeful case that this page is updated, here is a static image:


The issue with this article is that it appears to tie the port ranges for the Edge server to QoS which is not the case. You need to read the article very carefully. The first sentence in it tells you that you do not need to configure separate port ranges for Audio/Video/Application Sharing on the Edge. It then goes on to tell you how to change the port ranges to match up with what you may have set for your front-end servers.

The problem with this is that you are changing the ports that the Edge will/can communicate on. If you are following Microsoft’s firewall guidance on ports, you should be allowing the 50,000-59,999 port range (TCP and UDP) outbound. If you follow this example, you would need to allow the range 40,803-65,533 (TCP and UDP) outbound.

The article claims you might do this to make administration easier but I will claim just the opposite. Based on what most Lync admins know and what Microsoft states are the default ports, without some really good documentation and knowledge transfer, you are probably setting up a future admin to fail.

If you are wondering what happens when you set this like this but only allow the 50k port range outbound from the Edge servers, here is your answer. When an outside user attempts to call a user who is inside or join a conference, the client will send an Invite that contains SDP candidates. Those candidates will have ports associated with them based on the configuration. The external client will attempt to connect on ports outside of the 50k range that is being allowed on the firewall (i.e. 40,080-49,999 or 60,000-65,533). These connections will fail and the call will fail to establish. On a conference call, this can be seen as the user connecting and disconnecting from the conference several times in just a few seconds.

Many kudos to @tompacyk for helping me see what was happening here.

Thinking vs Hope

March 5, 2015 Leave a comment

The most dangerous words that come from my mouth are usually “I’ve been thinking.” When I think, my thoughts go everywhere. Most of the time they go to good places but when things get serious, when big decisions are on the line, my thoughts usually betray me. They go to the dark places of my mind. Fear creeps in and takes over.

I recently had a moment like this. It took a bit to recognize it but once I did, I knew that I had to refocus my thoughts. What I found was hope. We hope for things to come, things we don’t yet have. By focusing on hope, it becomes easier to see good outcomes. Hope for a better a situation, a better future. Hope.

My thoughts on the Microsoft Unified Technology Event

July 22, 2014 Leave a comment

Yesterday, Microsoft announced that they are not doing the smaller, product centric events like Microsoft Exchange Conference (MEC) or LyncConf. They are switching to a Unified Technology Event which will be next May in Chicago. You can read the announcement here:

This news isn’t all that surprising, combining efforts has to be a great way to save money and more efficient from a planning standpoint.

I have to admit, I’m sad to see LyncConf go. I went to both years of it and thought it was fantastic. I hope the new event is as good and not just a re-invention of TechEd. A few reasons that I am disappointed the smaller conferences are going away:

First, when you went to the product specific conference, you had a common bond with everyone there from the get-go. You didn’t have to find out what they were there for, they were there for the same product you were.

Second, because the conference was smaller, you didn’t feel like such a small part in it. It’s easy to let yourself get lost in a large conference and not engage with other folks.

Third, the networking was awesome. The conference was small and intimate and it made it very easy to identify people you wanted to meet. A larger conference tends to drive people to cliques and can make it much more difficult to connect with others.

Things aren’t all bad though. Having several products at one conference is great for a general sysadmin who has to work with Lync, Exchange and Office365 everyday. That person might only have the ability to go to one conference and now can do so (just like before with TechEd). I view this more as a negative due to the fact that I am more specialized and I could have used an extra day at LyncConf to begin with, add-in interesting content from Exchange or O365 and I may have even more tough choices in which sessions to attend.

Also, as someone who works for a consulting firm, it will be tougher for us to send folks. With the separate conferences we could send two people to each and not take such a hit from them being gone. With the Unified event, we will probably only be able to send a small selection and then the rest miss out on the experience.

I hope Microsoft does a great job with the event and makes us all forget about the small, intimate conferences but at the end of the day, I feel like this just like your favorite band. It’s great to see them either way but the small club was a much better experience than the large arena.
