RasMan Behaviour

[John Coutts]

Can anyone tell me why the RasMan service (Remote Access Connection Manager)
opens up tcp port 251 for listening. This port was not open when I first got
the computer, so it causes me some concern. I have disabled RasMan for now, but
I cannot use dial-up networking without it (only need it for testing). I can
start RasMan without a reboot, but I cannot shut it down. It must be disabled
and the machine restarted.

Is this normal behaviour for XP? All the other machines around here are 2000,
so I have nothing to compare to.

I have not ever seen rasman open port 251, and I have no
clue why it would want to.

Are you setup for Incoming Connections, or do you just
connect outbound?

Just outbound and ethernet. It took a lot of effort to determine that it was
RasMan, because <tasklist.exe /svc> only narrows it down to the group of
services running under svchost netsvc. I had to stop each service in the group
until RasMan was the only one left. It would not shut down, so I had to disable
it and restart. Then and only then did port 251 stop listenening. Start it and
port 251 starts listening again.

According to the registry this service usess RasMans.dll, and the properties on
this file are:
