[jcifs] Any improvement to DFS connections?

My testing (on a live system - so testing was limited) against Win2k/2k3
servers with XP clients indicated that before a client accessed any
share on the server it would try to do a DFS lookup - and cache this
result. This was on an AD domain - but I'd expect that the same would
be said against a 2k3 server not running AD.
If anyone is interested to test this and report their findings - it may
show that Windows doesn't magically know that certain shares are DFS..
You'll prob want to grab the dfsutil tool (from Win2k3's support tools I
think) and do a dfsutil /purgemupcache /pktflush /spcflush before doing
your packet captures. Or if you're super keen in wadeing through
captures - do it from the time a machine first joins the domain ;)
