kerberos           88/tcp    krb5 kerberos-sec      #Kerberos
kerberos           88/ucp    krb5 kerberos-sec      #Kerberos
microsoft-ds      445/tcp
microsoft-ds      445/udp

The traffic on port 88 stopped, after a while.  It's been a week since
joining the Windows 2000 servers to the domain, and they're still trying to
chat on port 445.  I've got that port blocked at the server (via ipchains);
even if it wasn't blocked the Linux server isn't running anything that
listens on that port.  The Windows 2000 servers are functioning just fine,
so clearly the microsoft-ds service isn't crucial.

I'm assuming it's a part of the Active Directory services; but I'm curious
why it's activated.  I thought that Windows 2000 would see the Samba 2.2
server as a Windows NT 4.0 domain controller, and thus operate in Legacy
mode (ie: no Active Directory).  Is this not the case?

Exactly (from /etc/services)
netbios-ns	137/tcp				# NETBIOS Name Service
netbios-ns	137/udp
netbios-dgm	138/tcp				# NETBIOS Datagram Service
netbios-dgm	138/udp
netbios-ssn	139/tcp				# NETBIOS session service
netbios-ssn	139/udp

if you have win2k you may also need port, hmmm 445?
