I believe I found a bug in the XenApp Powershell Commands (CTP2) that deletes the farm license server name and changes the port to 7168.

Edgesight alerted us that our XenApp servers were unable to communicate with the license server.

Checked the farm settings and found the following:

Who changed the farm license server setting?!  Someone’s about to feel the swift justice of configuration logging.  And the configuration log said…

WHAT?  This can’t be right.  The config log says I made the change to the farm license server setting!  I did some testing and found the configuration logs were correct.  I did make the change with some help from a bug in the Powershell XenApp commands.

I was running some XenApp Powershell commands this morning and was able to recreate the bug with the following command:

Get-XAServer -zone yourzone -OnlineOnly | Get-XAServerConfiguration

Bye, bye farm license server setting.
