Think I found the issue, since this core's DB was upgraded from 8.8 it was using the old scheduled task without the newer vulscan command lines, recreated it in 9.0 and all seems well.
I read your first post / question this morning and thought to myself "ZMAN is asking a question? He answers but rarely asks... if he doesn't know, who will?"
Glad you appear to have been able to find your own answer!
Have a good weekend
LOL - I ask a lot of questions usually talking to my multiple personalities I'm just like most people on the community, use the tool, have issues, try and resolve the issues. Just a normal LANDesk Engineer.
