DHCP Lease Query

[NickW]

We have a number of DHCP scopes on one server and all work
fine. All the leases show the unique ID as the MAC address
(which I would imagine to be correct).

However, we have one lease which has a very strange unique
ID of 3235...................400 (about a 20 character
string).

I have deleted this lease and it reappears almost straight
away and also the name shows as the IP address and not as
the DNS FQDN as the other leases do.

I cannot ping the IP address of this lease either.

Any ideas ?

Thankyou

Something else I have noticed is that all the printers

that were reserved have all received new addresses that
are not reserved.

All these problems occur in the same scope as well.
