I installed a new oes2015 server.. everything is working as expected for NCP and AFP connections...I cannot mount the NSS volume via cifs.. I have all the contexts in the search pattern. etc ... Same contexts as my OES11SP2 servers...When I attempt to connect via cifs the cifs log shows the following errors... anyone have any ideas ??
