SBS DHCP not listening...

Hi

We set up an SBS 2k3 R2 server and DHCP was running smoothly. But
yesterday at some time (no errors in the event viewer) it stopped
giving out new addresses and the clients requesting IP addys got no
reply from the DHCP server. Existing leases are honoured though, but I
suspect thats just cached info on the client machines. I watched both
Network Monitor and the DHCP server stats while doing an ipconfig
/renew, and I receive *BROADCAST packets from the MAC of the requesting
client, but the DHCP stats show that there have been no new requests!
I've tried stopping the ISA firewall service in case it was that, but
it still doesn't work!

Any ideas?

Thanks!
James

Did the ISA come with it on the Install CDs or did you install a standalone
ISA on the SBS box?

Does the Live log in ISA show anything "denied" during the attempt?
