NIS 2009 and Windows XP Security Center problem

Firstly, thanks for the hotfix for the ‘Symantec Service Framework’ error. It’s worked fine for me and everything seems to be normal again now… apart from one thing! This is more of an irritation than a problem, but the Security Center now says that I have no AV or firewall installed, so I’ve currently got it set to indicate that I’ll monitor these things myself. Before the recent error Norton was recognised by the Security Center. How can I get it to recognise NIS 2009 again please?
