When a incident forwarded from OVO to SD a db-rule is triggered. This db-rule uses cscript and the ovo-sd.vbs to set ownership, create annotation etc. Open the db-rule in SD admin console and find the action that sets the annotation. Try to run the command from a command line on the machine in the "host" field.
If this works then most likely the db-rule does not trigger or the SD-agent is not running.
If it does not work, you should have a error message.
Hope this get you any closer to finding the cause.
