DHCP: unable to add a reservation

[Guest Oliver]

Something's got wrong by adding a new DHCP reservation:

- the reservation is currently not shown

- neither the IP address nor the MAC address is shown in view “Active Leasesâ€

- when I try to repeat the reservation, I get the error “An error occurred

while accessing the DHCP database. Look at the DHCP server event log for more

information on this error.

- on DHCP server event log is nothing related logged.

- the client gets no address by booting or ipconfig /renew.

- event log of the client has logged first, that the requested IP address is

currently in use by another client (warning). After rebooting a lot of

DHCPNACK’s are logged.

- I did a backup of the DHCP database and edited it with a HEX-Editor. A

search for the MAC address is successful.

- I did already a reconcile and a restart of the DHCP service.

 

Conclusion: I assume that a corrupt entry of the reservation is stored

somewhere in the database. But I’m not able to manage it.

 

Server is a W2K3 SP1 server.

 

How can I resolve this problem?

 

Thanks, Oliver
