These are all ports commonly blocked by ISPs, like NTL do in the UK.

I did a nmap scan on one of my users home systems. Its a typical
broadband connection default TCP scan revealed port 21, 25 and 80 open.
In the past I've found that these ports belong to the broadband modem.
I then did a -sU default UDP and found the following:
PORT STATE SERVICE
135/udp filtered msrpc
136/udp filtered profile
138/udp filtered netbios-dgm
1434/udp filtered ms-sql-m
135-138 typical MS stuff no?
1434 I know the user is not running SQL monitor. Is it likely the
system has SQL slammer/Sapphire running on it?
The system is XP home SP2
