Lync SBA’s: The Good The Bad, and The Annoying

If you’ve deployed Lync Enterprise Voice, you’ve at least had a discussion around Survivable Branch Appliances. You may have even deployed them. After having deployed (or assisted in deploying) and supported over 25 of them I’ve learned quite a few lessons about SBA’s that I thought I would share. First off: sizing. If you look …

Moving Immovable Users

This is probably the first of a few blog posts regarding a problem we are facing with our Lync 2013 environment. In short, we have 2 corrupt routing groups right now. Users assigned to those routing groups are unable to add a contact to their buddy list and they cannot change their status. This tip …

Quick & Dirty – Gather Shutdown Tracker Events

Today I had the need to see if my Front End servers were shut down “dirty’ and when. So I kicked out the following script.

Port 5088 Missing from Lync 2013 Documentation

We had an issue where users were able to sign in with Lync mobility but were unable to send and receive IM’s. There are 2 things to note about this scenario: 1. The users are homed on an SBA 2. There are firewalls between the SBA and the parent pool. So if you don’t have …

Lync 2013 and Useless(?) Topology Updates

We noticed today (and a few days ago, for that matter) that our CMS Replication state was “False” an awful lot of the time. So much so that we thought our CMS Replication was broken. We failed over our CMS role1 the other day and, after coming back from lunch, all of our replicas were …

New Windows Phone UC App

About 2 years ago I released the Lync News app for Windows Phone. Today that app has been retired and replaced with “flinchböt on UC“, an app which covers Lync as well as Exchange and has a fairly terrible name (I was in a hurry and didn’t give the name any thought.). The new app is …

Fun with KHI and Performance Monitor

A few weeks ago I wrote a post basically saying that the Lync Stress Tool was worthless. In it I said you should really monitor the progress of your Lync deployment using Performance Monitor. I also pointed to the Key Health Indicators  that Microsoft recommends you use to monitor your Lync installs. Heck, they even …

Find SIP Addresses with Illegal Characters

One of my peers had a Lync 2013 pool-failover scenario. Just about everything worked right except that apparently the Lync Backup Service had been getting hung up and not completing its replication cycles. They opened a case with Microsoft and one of the issues discovered was that Lync Backup Service was hanging on users whose SIP …

Disabling HTTP in OWAS/WAC

We built our OWAS farms and, like most Lync people, had no clue what we were doing. But they ended up working anyway so hooray for us. Now that we are begrudgingly learning a little about it we have learned that we should disable HTTP on the pools and run with HTTPS only. So we …
