Anti-Virus Update problem?

I have McAfee VirusScan Enterprise 8.0 or 8.5 installed on all Windows PC's in our network. They are all up to date. WMI & DCOM are configured and I get information about both workstations and servers.

When running Anti-Virus V&S Overview (great report) all servers  show as being not up-to-date while all workstations are up-to-date. The servers also do not report AntiVirus name and AntiVirus version, probably for the same reason as they show as not up-to-date ...I also have the default Spiceworks Monitors and Alerts trigger AntiVirus is not up-to-date active, but this indicator is not triggered.

What do I need to do to get rid of this incorrect indication of AntiVirus not up-to-date?
