Open ports

Hi there, I recently ran a scan on my Web Server (SuSE 6.4), and in addition to the expected TCP services (http, ssh, smtp et al.), it claimed that the UDP ports 135 (msrpc-epmap), 137 (netbios-ns) and 139 (netbios-dgram) were open. I can see no reason why they should be - they are not enabled in inetd.conf(I ran harden_suse when i first set up the machine), and I am not running Samba. The only "non-suse" thing that I am running on the machine is Chilisoft-ASP, but I cannot see why that would have MS specific ports open. Does anyone know what it might be that returns this result? Many thanks, Iain
