VPN Disconnect

[msnews.microsoft.com]

We have a 2003 VPN server set up with a Pre-Shared Key. Works pretty well
for most of us.

A handful of users are getting disconnected 2-3 times a day and cannot get back in for 5-10 min.

I see no correlation between disconnects i.e. it happens randomly.

I suspect their connections. One is dial-up and the others are various
forms of broadband.

At the time of disconnect I just get an Event ID 542 in the Security log. It says IKE security association ended. While she is trying to reconnect I see an Event Failure 547.
Failure Reason:

IKE SA deleted by peer before establishment completed

for her IP address.



After 10 min of trying she connects again.



Any ideas?

You might want to post this to the
microsoft.public.windows.server.networking or security group.. This
is a relatively new issue...

Just for curiousity, are you trying to run IPSEC with NAT traversal?
I have seen this with a NAT-T link, but not with a pure IPSEC tunnel.
