Here is the main problem. On server initialization, all known interfaces
are registered to xdmcp. Normally there would be at least two other entries
with ifname = eth0. 
The error seems to be in a cygwin ioctl function. The code which calls
t is in os/access.c and is (roughly) this.

int fd = fopen("/dev/ip",O_RDWR, 0);
ifnet.ib_next=1;
while (ifnet.ib_next) {
    str.ic_cmd = IPIOC_GETIPB;
    str.ic_dp = (char *) &ifnet;
    ioctl(fd,I_STR, &str);
}

In some cases, the ioctl will only work for the loopback device. Maybe some
of those who are familar with the cygwin network code can give me a hint.
