DCM configuration packs in released Security Compliance Management Toolkits are Operating System Configuration Items. They work only on Vista RTM. We are working on an update to support Vista SP1.
If you can't wait, there is a workaround, you can duplicate the baseline and change OS version from 6000 to 6001. This may be lots of repeat changes for every CI (configuration item) so you can consider to export the baseline and edit them in XML (but you have to pack them into cab before you can import though). In XML, this is line like,
<OperatingSystemDiscoveryInfo BuildVersion="6001" MajorVersion="6" MinorVersion="0" />. I hope this helps.
Thanks,
