Our business runs on SBS 2000, and for some time I have been aware that the SBS DHCP scope (192.168.16.0) has been full, with 245 total addresses and 245 in use, with 0 available. I had assumed that this was because we have 15 clients connected and 15 licenses installed, and perhaps SBS was tying up the others. These 15 clients were using all available address leases, and deleting one would open up a lease for another client to log on. I recently purchased an additional 5 licenses to add more workstations, and discovered that we already had 20 licenses installed, and the additional 5 brought us to 25 licenses, but didn’t free up any more addresses in the SBS scope. Of course, this means no other workstations can join the domain, even though we have 10 licenses installed and unused. We are now urgently needing more than 15 clients at a time logged on. Any ideas?
