CMS Replication Issue to Edge Server


Today I came across a CMS Database Replication issue that had me scratching my head for a while.

Scenario is 2 sites with SE and Edge each, the first site I setup a few months back and was expanding with the new site. For the sake of explanation I will call the existing site #1 and the new site #2.
All servers were replicating except for the #2 Edge Server.

I ran through the obvious checklist as follows:-

  1. Edge Server has a valid Certificate
  2. Edge Server can reach internal CA
  3. Edge Server is able to resolve Lync FE
  4. Can Telnet from FE to Edge on port 4443

No joy..So I ran the XDS Trace on the Logging Tool. It was at this time that I realized that the usual 3 XDS trace components were missing as below:-

So where are the other 2 trace components?
It was at this point that the lights went on…the Lync Server I was tracing on (#2) was not holding the CMS! Embarrassing. So I launched the logging tool on FE #1 and what do you know:-

So what did the trace reveal? It showed how Edge Server #2 was not responding. So I suspected that although I had tested Telnet access from the #2 FE to #2 Edge – I hadn’t tested connectivity from FE #1 (where the CMS is) to #2 Edge.

My suspicions were confirmed, a quick chat with the networking boys and voila.

About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
