I have a couple of systems with Samba 3.0.6 installed on Fedora 1. One as a
PDC and the other as just a member server in an AD. Both have been updated
incementally since 2.2. The PDC system has the net tool installed, the other
doesn't. Is there a reason why it's not installed and how do I install it ?

I've been using the binary rpm for Redhat/Fedora to upgrade.
