EnableSessionTicket from Powershell

To get support for Lync and Skype for Business on Windows Server 2012 R2, you need to add a registry key that changes TLS session caching on 2012 R2 Server. This is described here https://support.microsoft.com/en-us/kb/2901554

To create this key, use the following powershell oneliner:

PS Oneliners: Set Skype4B services to manual or automatic startup

If you need to reboot a Skype for Business server, you might not always want the services to start automatically afterwords for various reasons. For instance if you are doing a shutdown of an entire pool, you’d want to run

Start-CsPool -PoolFqdn skypepool.contoso.com

to do a cold start of the pool, instead of the services starting automatically.

Use these oneliners to set the services to manual startup and back again to automatic afterwords.
