Here's what I learned from strace:

The Network Status is it's own program called PokerStars/Tracer.exe so it's
easier to debug just running "wine Tracer.exe" from the PokerStars directory.

There are no permissions problems (at least, not while running as root).

Tracer.exe uses ICMP.DLL

Tracer.exe (or ICMP.DLL) creates a bunch of threads. Each thread opens an ICMP
socket with:
[pid 14388] socket(PF_INET, SOCK_RAW, IPPROTO_ICMP <unfinished ...>
[pid 14388] <... socket resumed> )      = 23

The socket is opened successfully. Each process probably corresponds to one
ping operation.

Later the socket is shutdown but now there's an error:
[pid 14404] shutdown(23, 2 /* send and receive */) = -1 ENOTCONN (Transport
endpoint is not connected)

I figure that ICMP.DLL (ICMPCreateFile) must work sometimes or we'd have more
bug reports about this. Maybe the issue is that it doesn't work within a
thread?

I'm not a windows programmer so I don't really know how threads or sockets work
under windows. It would be nice if we could get a windows programmer to create
a test case which:

1. Use ICMPCreateFile to do a ping in the main process.
2. Do an exec (or the windows equivalent)
3. Try ICMPCreateFile in the child process
2. Do a fork (or whatever windows equivalent)
3. Try ICMPCreateFile in the thread.

If my theory is right then ICMPCreateFile will succeed in the main process and
succeed in the child process but fail in the child thread.
