Have limited ip pool with 4 more addresses than I need. Have a 3 day lease
on ip's. It turns out that when the wrkstations are booted and ask for a
new lease that there are not enough avaible. Using the management console I
notice that all available addresses are taken but not all the addresses are
assgined to hosts. That is there is a mac address listed but no host name.
So, it seems that dhcp thinks it has assigned the address but the wrkst
doesn't have an address. If I go to the wrkst and put in a static ip
address it immediately has network resources.

How can I troubleshoot to see why and how ip's addresses are being assigned
but not not functioning on the wrksts?
