I have been using CIPE on W2K connected to a Linux Box for more than a year
now and have experienced tunnel instability (every now and then the tunnel
connetion breaks down (no pings go through) and is restored by itself after
a few minutes (pings start flowing again)).
Are the MTU and KeRaiseIrql fixes mentioned above already included in
