[pptp-server] Authentication to an NT domain

[Mathieu Martin]

Hi,

    I've got PPTP working for a client. Everything works fine, except
for the authentication to the NT domain, that sometimes works, sometimes
not.

When the client connects through PPTP, he gets a dialog box asking for
his user,password, domain. He enters the informations, presses ENTER.
Then, if he's lucky, it authenticates well and his network drives are
aothmagically mounted.. If he's not lucky (most of the time), he gets an
error message that looks like this: "There were no server available for
authentication".

I tried assigning the WINS server via PPTP. The ip of the WINS server
then shows in "winipcfg", but I still have the same problem.

I noticed that, when I connect to the PPTP server, I can't get an answer
for the first ping I do to every ip addresses. I mean:

I connect.
I ping 1.1.1.1. No answer for the first ping. Normal answers for other
ping's.
I ping 1.1.1.2. No answer for the first ping. Normal answers for other
ping's.

Could it be related to my problem? What could be causing that?

Thanks!
