What has been changed recently as I assume this hasn't happened until recently?
Thank you for your reply. LDSD 7.4 worked normally before. I had installed recently LDMS V9 in the same Server of test ( Windows server 2008 R2). During the test period of LDMS , I hadn’t use SD so I don’t know exactly when the error appears in SD ?
I suspect those two events are related. I'd recommend you log a support call.
