[ale] any used pptp client?

Has the computer been part of the domain before?

Put the domain controller's name/IP into the lmshost file
of your workstation.

Subject: [ale] any used pptp client?


I'm trying to connect to a corporate vpn via pptp, which is Microsoft's
solution for vpns.  What I think is going on is that I'm communicating
with the vpn server okay, but the domain server which is supposed to
auth. me is not responding.  I'm hoping some of the network gurus out
there can look at the info that follows and at least tell me if I'm
right.  At least at that point, I'd know where to start digging.  I can
put an incorrect secret in my chap-secret file and I don't see anything
different in the logs, so that's why I believe the domain server is not
responding.

The way this is set up in my chap-secrets file is as follows:

client                server           secrets    ip
DOMAIN_SERVER\\my-id IP-OF-VPN-SERVER  MY-SECRET  *

Any insights would be greatly appreciated, since, if I get this working,
I can continue to stay Microsoft free in my remote work environment.

Here's what I see in daemon.log:

Jan 15 15:37:03 a (unknown)[27589]:

Jan 15 15:37:48 a pppd[27626]: Connection terminated.
Jan 15 15:37:49 a pppd[27626]: Exit.

So that looks to me like the server is not responding to my LCP
requests.


Here's what I get from tcpdump:

1 0.000000    denali.atlnet.com     VPN_IP          TCP      1044 > pptp

[ACK] Seq=1814069342 Ack=829577 Win=32120

I don't know that much about this protocol, but what I see above looks
like everyone one's happy.  Suggestions?  Insights?
