We are using LMS 3.2 (Campus Manager 5.2.1) and I just installed User Tracking Utility v2.0. I used an older version of UTU successfully before we moved to Vista and then stopped using UTU because it was not supported. After installing UTU v2.0 I am able to successfully search for end hosts by mac-address but any searches by IP address returns "No Records Found". Are there known issues with using v2.0 on a 64 bit client version of Vista?
