We have a NetWare 6.5 DHCP server, and the lease is three hours. Every workstation should have a different IP address each morning when the user logs in after shutting down the workstation at night.

About 50% of the workstations get a new IP address each morning. The other workstations keep the same IP address. All workstations are configured to receive IP addresses via DHCP.

I have not found any difference in the workstation configurations to give any hints.

Where might I start looking.
