how do you know it? what is your problem exactly, ip pool is 100% used or workstations get the same ip address everytime they try to renew ip?

Normally when a lease expires the DHCP Client will ask for new lease and if, as in the previous answer, the IP Address table is not used up 100% and if the same previous IP Address can still be alloted or there are no conflicts, the same old IP Address is alloted/leased

What is the lease duration? A Windows client will always ask to renew its DHCP lease at set intervals (i.e. 1/2, 3/4, 7/8 of lease). For example, a client with an 8 hour lease will attempt to renew when 4 hours (1/2 of lease period) have passed. If successful, it will have the lease for another full 8 hours...it will renew again when 4 hours (1/2 of the current lease period) have passed. When the client renews, it get a full lease again. So depending on your server's lease period, your clients may be renewing throughout the day, keeping the IPs tied up.

Cheers,
Sean
