Microsoft Teams Deep-Dive – Canberra follow-up

I presented a Teams Deep-Dive session at Microsoft’s office in Canberra this week.

At the end there were a few links I wanted to share with the participants, and a few homework questions I wanted to research and respond to. A blog post seemed the obvious way to provide them with that info.

The below will be of greatest relevance to the attendees, but even if you weren’t there I think you’ll find some bits of interest.

Cscp logs Event 35009 – “Authorization Failed”

My colleagues and I recently encountered an intermittent problem with the CSCP reporting “Authorization Failed” when you tried to sign in.

This was a Skype for Business 2015 Enterprise Edition pool, and so it didn’t take long to localise the issue to just one Front-End server.

Each failed attempt dropped an instance of event 35009 into the “Lync Server” log:

Remote PowerShell cannot create InitialSessionState for user S-1-5-20. Cause of failure: Cannot find user in Active Directory with the following SAM account name: "S-1-5-20"

That SID belongs to the NT Authority / Network Service – and when we succeed on another machine, we see the traces* correctly trying to sign in as the SID of my admin account.

(* The reference to PowerShell in the log gave us cause to review the Centralised Logging for the “PowershellWebService” scenario, but it didn’t seem to add a great deal of value.)

A successful sign-in also drops the more friendly 35008 into the log:

Review: Poly EagleEye Mini USB camera

I’m a little late to get my mitts on an EagleEye Mini USB camera, but circumstances recently gave me cause to take a closer look.

If you’ve not encountered it before, the Mini is a compact 1920×1080 HD USB camera, initially designed to slot into the top USB port on your VVX501 or 601, but nowadays also supported on a Trio with Visual+, and even on a PC or Mac.


Poly’s website reports its features thus:

  • High-definition 1080p60 capture with true color hue saturation and brightness for the most accurate color rendition and life-like images
  • 4x electronic zoom and a 74-degree field of view
  • Simulcast video stream
  • Installs in seconds – no drivers needed

It’s officially a supported peripheral for Skype for Business video calls on a computer or video conferencing device.

I have the occasional need to send log files to Microsoft and other vendors from customers who have strict IT security requirements. These customers usually require all files be de-identified before they leave the premises, removing all host names and IP addresses.

This can be quite a tedious process, so I’ve created a small script file that edits a provided text file and:

  • uses a “find/replace” CSV file to replace all instances of sensitive text with replacement values.
  • obfuscates any unchanged IP addresses, replacing them with dummy text in the format “aa.bb.cc.nn”, where the “nn” is the same number where-ever that IP address is encountered in the document. (e.g. the third IP address that’s found in the file will be renamed “aa.bb.cc.3”).

At a minimum, you only need to provide an -InputFile. With only this, the script will replace all IP addresses with dummy values, then save a copy of the file with a “-new” suffix.

Azure – Resource Provider Not Registered

I’ve been following one of Tom Morgan’s excellent tutorials on creating Bots for Microsoft Teams, and I hit an unexpected hurdle very early on in the process – but as it turns out, the fix was a simple one.

Resource provider 'Microsoft.BotService' not registered for the subscription

Fair enough, I say. Let’s register.

I navigated to All Services then searched for and selected Subscriptions, then selected my Subscription and Resource Providers. There were a lot there, so I filtered for microsoft.bot, only to be greeted by the news that I *was* already registered:

Seeing as I was already here and there was an option to Unregister, I went down that path. Refresh, wait a bit, Register and BOOM, I was back on the air.

The moral of the story? Even in the cloud, turning something off and back on again remains a viable fix.

Yes, I’m gay. Why even mention it?

Occasionally someone will be brave enough to ask why I give my sexuality top billing in my Twitter profile and bios:

It probably seems a little out of place given that if you search the word “gay” on my blog you’ll find the only hit – singular – is on my “about” page (until now that is).

That I’m gay isn’t relevant to what I do for a crust – no questions about that.

It’s purely a visibility thing.

Test-CsDatabase shortcuts

I don’t know about you, but I’m not getting any younger, and my eyes often glaze over when faced with a table of numbers to compare for differences.

This is often the case when I issue one of my fave p$ shortcuts to test my SfB server’s databases:

Test-csDatabase -LocalService | ft *name,*edver*

Do this on every server in a large pool – or every server in a vast environment – and you might start to experience the same optical distress.

Here’s a variation on the above that ONLY reveals the Databases that fail to match:

Test-CsDatabase -LocalService | where-object {$_.InstalledVersion -notMatch $_.ExpectedVersion} | Select *Name,*edVersion

Replace “-LocalService” with “-ConfiguredDatabases -SqlServerFqdn”, etc, for an Enterprise Edition pool and for Monitoring or Chat databases. (Cmdlet reference).
