Systems Management

Here's my situation. I advertised a package (mandatory assignment) to 50 clients at a single site, stating that the package would be available after noon. Before noon, I realized that a couple of the clients should not be given that package. As a temporary measure, I disabled the program and removed the package from that site's distribution point.

The clients reported "10002 Program received - no further status"

I removed the 2 unwanted clients from the collection involved. I'd like to enable the program and let the other 48 proceed, but I worry that somewhere the other 2 are still on a list to get the installation. How can I be sure they will not?
