Re-installing MCX

While attempting to repair a problem with a clients self installed Lync FE IIS services I came to the conclusion that the Web Components Services was broken. No problem, right?
Simply uninstall the Web Components and then re-run the Deployment Wizard. I did that and returned to IIS to see MCX now missing. Suppose I should have expected that. No problem (again), I’ll just run the MCXStandalone.msi…
So the .msi says that the MCX is still installed, did a remove and ran it again to re-install. Done.

Checked IIS and MCX has returned, only problem is it still doesn’t work when I run the test.

So what’s the issue?
For one thing, the Environment had been installed and updated to CU6 but the MCXStandalone was still on the relative CU4. The MCX Update was found here

Secodly I assumed that the MCX listening ports were still defined as you usually cant install the MCX if they aren,t. Better safe than sorry, so I re-ran them too

Set-CsWebServer -Identity -McxSipPrimaryListeningPort 5086
Set-CsWebServer –Identity  -McxSipExternalListeningPort 5087

I restarted all the services for good measure, probably wasn’t necessary.

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.
