When the Terminal Server MP is loaded for monitoring Windows 2008 based terminal servers the Alert ‘Communication with TS Session Broker’ might pop-up. The Alert Description is as follows:
Event ID: 1014 -- Description: The server failed to retrieve the security identifier (SID) of the TS Session Broker server. Win32 error code: 0x534.
After some searching the cause seemed to be that the FQDN was used for the TS Session Broker name in the GPO, assigned to all W2K08 based terminal servers.
After changing this FQDN to the HOST name all was well again and the Alerts didn’t come back.
