Seemingly random disconnects. I haven't been able to find a consistent

This is from various remote locations. When it is up it works normally,
mapping and using drives, etc. I'm looking for ideas... thanks.

W-XP client, W2K3 Server. All up to date with patches/fixes.

Obvious but have you checked the options for the connection and made
sure the idle timout isn't set ?

Yeah. Although I can't remember what it is now. But... the disconnects
don't happen at consistent times. So I don't think that's the problem.

Have you tried running a continous ping across the connection to keep it
running ?

No. I've read of folks that do this. But... if that's what it takes to
make MS PPTP work I would choose not to use it anyway. There are other
more stable alternatives. But not free :)

You could also try the vpn connection across the local lan, if this is
stable then it points to an internet/isp issue.

Very good idea! I'm doing that now as we speak. However, I have tried
this from various wireless locations (which obviously use different ISPs)
with about the same results. Anyway, if it works well over the local
LAN, I my be even more confused :) [Note: still up after 10+ minutes! -
Hmm...]

BTW, I also use the Kerio Winroute firewall with comes with a VPN server
and VPN client software. The VPN sulution does not suffer from the
disconnects like the MS stuff does. All from the same locations using the
same server machine. I don't know.

Of course, the Kerio solution costs $400+ (LOL). I like the product and
use it for my own business. But I was hoping that the built-in MS stuff
would be a free solution for some of my customers that don't really want
to purchase an enterprise class firewall product.

Thanks for your input.

Hi Frank,
I have setup windows VPN servers that had 90+ concurrent VPN connections
to them. Very rarely would we get dropouts. If we did it was invariably
due to the clients dsl connection, the servers were connected via a 34mps
E3 that was pretty rock solid. I have had a pptp connection running for
days at a time, so in the right environment it's pretty stable. It may be
that it's more sensitive to internet issues than the kerio client, how was
the test over the lan ?
Shame the server isn't SBS2003 as this offers remote web workplace which
is so much better than VPN for most applications.

Thanks for your input Simon... appreciate it. The test over the LAN was
fine. So... I'm gonna have to attribute the flakiness to the dsl connections
I was using. To be fair, I only tested it from a couple places. So that's
probably it.

I do appreciate knowing that from your experience the built-in W2K3 VPN
should be relatively stable over good connections. Thanks!
