I'm running a number of Windows XP clients connecting across ADSL lines to a
VPN server running Mac OS X Server (10.4.5). The clients make PPTP
connections to the Apple server, and then access resources on the local
network, including file shares on a Windows SBS 2003 server. The users are,
for some reason, getting disconnected from the VPN after a while; sometimes a
few minutes, sometimes as much as eight hours. The OS X server logs report
this:

My servers are behind a Draytek NAT router, but I've tried it with a Netgear
too, so it's unlikely to be the router. Some remote workers use NAT; some
have directly-connected (USB) modems. All use XP Pro SP2. Since they can
connect and use the system for a while before it chucks them off, I'm not
sure how much of this is network-related. I've asked about on the Apple
forums but I thought I'd check here if anyone's had similar experiences/knows
of a useful fix for Windows XP. I've checked idle timeout settings, but the
fact that it's not disconnecting cleanly and that the XP box seems to be the
ones dropping off suggest a Windows problem. Any help would be welcome, as
I'm approaching my wit's end with this issue...
