After someone made a VMware clone of a 2008 Terminal server I was asked to create a TS farm. After creating the farm one of the secondary servers would not join it. After looking in the System Log I found the following:
The server failed to retrieve the security identifier (SID) of the TS Session Broker server.
Win32 error code: 0x534.
After thinking it was an error due to not running sysprep, that was not the case.
I was using the FQDN for the TS Session Broker server name which for whatever reason was causing this error. After removing the FQDN and only using the hostname on both the TS Session Broker and the additional server, I rebooted and the server joined the farm without any problems.
