We accidentally click on the dhcp service and it got uninstalled.
I installed it back on the server and all my settings were lost. I
recreated my superscope and now it doesn't appear to be releasing IP
addresses. Fortunately, my backup dhcp server is working, so I went ahead
and increased the scopes on my backup.
In the mean time, does anybody have any suggestions or ideas on what I could
missing.

Thanks in advance for you help.

Hi

Maybe this will help

SYMPTOMS
===========
When a client and server are on different subnets and the server does not
have a scope defined for its local interface, the Windows 2000-based
Dynamic Host Configuration Protocol (DHCP) server may not release an
Internet Protocol (IP) address when the client sends a DCHP release
message.

CAUSE
=======
This problem can occur when the DHCP server evaluates the server's IP
address instead of the client's IP address that is requesting the release.

RESOLUTION
=============
To work around this problem, create a scope on the same IP subnet as the
primary DCHP server's interface. The presence of the scope works around the
problem. The scope does not have to be active. You can also manually delete
the IP leases by using the DHCP Microsoft Management Console (MMC).
