So, how are your host names resolved? Any changes in DNS or WINS name servers? Did anybody reboot or alter PDC? On NT host names are resolved by asking PDC . If it cannot respond because of reboot, listener may shut down as well. You should try modifying yur local equivalent of nsswitch.conf. whatever the name is.
