DHCP not leasing new addresses

[llefebure]

Greetings everyone:

I think I've found a bizarre little problem with DHCP in windows 2000.

Problem:
You have a Windows 2000 server serving DHCP addresses to clients. The DHCP pool runs out of addresses so you add some more. You do this by either expanding the range, or deleting some exclusion ranges. The server continues to hand out addresses to existing clients, but new ones are unable to get an address.

Troubleshooting:
I've seen this twice in the past week - 1 server was SP2, the other SP3. Both were running active directory. I stopped and started the DHCP server service. I deauthorized and authorized DCHP within active directory. No luck getting it to lease the new addresses. It will however give an existing client an IP if they do a release and renew.

Solution:
Reboot.

check the lease time on both, the old ones and the new ones..usually i have the leases for 6 hours, that way computers dont get stocked with the same ip addresses all the time or for a long time, and at the same time it makes available other IPs, and also the dinamic of assigments. A+, MCP, CCNA
