DHCP Scope address pool exhausted
Hi,
I have the DHCP service enabled on a Win2000 Server, SP4. It has an address range of 192.168.200-192.168.0.250 issuing around 9 machines with IP addresses. Recenlty, some machines have not been able to access the network. The server system log has warning entries 'Scope, 192.168.0.0, is 100 percent full with only 0 IP addresses remaining. ' and entries in the DHCP log '14 A lease request could not be satisfied because the scope's
address pool was exhausted'. However, under 'Adress Leases' there are only 6 in use.
Also, there is an entry in the DHCP log '02 The log was temporarily paused due to low disk space.' however there is over 80gb free space available on all server drives.
Any help would be appreciated.

The DHCP database seems corrupted. Note down all relevant parameters for your scope, then delete it in dhcp manager, and then re-create a new scope with the same paramaters. That should fix it.
192.168.200-192.168.0.250
This is actually a verry weird scope setting. Also check your subnet setting for the network class u are using
ex.
192.168.0.200 to 192.168.0.254
with subnet 255.255.255.0 gives u 54 Adresses. (class C)
but u also want to check the lease time given by the DHCP server, This leasetime will reserve addresses given to "guest" machines for a 'defined' time. So if this time is '1year' (verry long - usually 1 week -> 1 day) and i log 54 machines on to the network the scope will indeed be exausted.
So check if your range setting is correct, and check how long a lease lasts..
