Backup fails on System State:\Terminal Server Licensing\TSLSComponent

Hello

We have 3 Windows 2012 Core Domain Controllers

The two with Terminal Server Licens is failing with

WRN - can't open object: System State:\Terminal Server Licensing\TSLSComponent (WIN32 -536832991: Unknown error) on the Shadow Copy Components:\ backup

And the third DC is runing without any issues

Have checked the writers which are OK and run succesfull backup of system state with the wbadmin tool

Have other seen a similar issue with the Terminal Server Licensing object ?

Netbackup Client 7.5.0.6

Regards

Michael
