QC Site Admin does not show total UFT/QTP licenses in use; rather, the Connections tab shows if a UFT/QTP client is connected to QC. The QC and UFT/QTP licensing mechanisms are entirely different, so all QC Site Admin can show is if another testing tool is making a connection (regardess of what actual licenses are in use). In other words, QC Site Admin cannot and will not show QTP/UFT licenses in use.

WlmAdmin, by contrast, shows QTP/UFT licenses in use (regardless if a QC connection is made). This includes users who open QTP/UFT manually to work in the application, and also if another tool (like QC) opens QTP/UFT for running an automated test.
