Install-WindowsFeatures Fail Server 2012R2

So after attempting to use Pat Richards Lync install script (http://www.ehloworld.com/1697) I was seeing errors on the Lync FE server that Lync prerequisites were failing during the install.

After some trail and error of individual features I was able to narrow it down to two (2) features that were failing;

• web-asp-net
• web-asp-ext

So off to Google to find an answer, first post was from Greig Sheridan (https://greiginsydney.com/add-windowsfeature-fails-on-server-2012/), the patch that Greig and co. had identified wasn't install on my 2012R2 server.

After a few discussions with colleges around what could be causing the issue it was found to be another windows patch that was stopping the install.

So after we removed the patch from the server, the install worked with no further issues..

RTCXDS 16 GB Transaction Log Limit Reached

I always have to go and look for the SQL query to check for the log database size, so figured that I would create a post to use as a pointer to Tom Pacyk blog on the issue.

The Query itself is;

DBCC SQLPERF (LOGSPACE)

Lync Callback Reminder

Two blog post in one day, I don't think that has happened before..

Graham Cropley has written a nice little plugin that you can set "reminders" from the Lync client for a call back to a Lync contact..

Deploying SEFAutil for Lync

This is a quick guide on how to install the SEFAUtil tool onto an existing Lync 2013 Standard Edition FE Server, at one stage this wasn't supported but I'm not sure if that still the case..

Software Required:
Microsoft Unified Communications Managed API
Microsoft Lync Server 2013 Resource Kit Tools (SEFAUtil tool in in this)

Once the UCMA software is installed you will need to create Trusted Application Pool:
New-CsTrustedApplicationPool -id fe2013.myucthoughts.local -Registrar fe2013.myucthoughts.lcoal -site Site:1

Define the SEAFUtil tool as the trusted application
New-CsTrustedApplication -ApplicationID sefautil -trustedApplicationPoolFqdn fe2013.myucthoughts.local -port 7489

Enable the newly created topology
Enable-CsTopology

Once the Trusetd Application Pool has been created you can then install the Lync 2013 Resource Kits

Remember to change the values required from my lab FE server "fe2013.myucthoughts.local" to what your server/pool is called.

Hint:
So I have was having issue with when running the sefautil command i would receive no information back from the FE server, this would found to be a typo in the new-trustedapplication cmdlet, I had typed "-applicationID seafutil" rather than the "-applicationID sefautil" that the command is actually called.

I have also seen blogs with users not having the correct permissions to be able to run the sefautil command will also receive the same output.

I had some time today to catch up on things so was checking the usual blog list that I read and came across this excellent article by Johan Delimon.
