DHCP Lease Expiration... Infinite??

[Guest]

Trying to understand how this could happen. We have a DHCP Scope (/24) on a
Windows 2000 Server. Standard installation, nothing special, except we have
the "Lease duration for DHCP clients" Limited to: 4 hours.

When viewing the Address Leases, most of them will expire in 4 hours... but
a couple of them have a "Lease Expiration" of Infinite.

How can a client get an "infinite" lease time when our scope says clients
are limited to 4 hours?

How can we prevent clients from getting a lease time different than the
scope permits?

Scope Options > Advanced have the following values:
Vendor class: DHCP Standard Options
User class: Default User Class

And our scope properties are set for "Assign IP addresses dynamically to
clients of:" DHCP only

We have a different scope servers and printers, nothing but short term
clients should be in this lease.

Thank you for all your help!

One more note I forgot. These addresses with Infinite lease times are not
DHCP reservations nor are they in an excluded address space.
