[xdebug-general] Problem connecting xdebug server to client

Hi all,

I've been spending the past hours trying to get XDebug to work.
Finally, I found this message in the mailing list archives. I could've
written it myself, it seems to be the exact same problem. The only
difference is that for me, this is the first time I am setting up
XDebug.

Tearing my hair out.  On a local Windows XP sp2 machine, with apache &
php 5.2.5, xdebug v. 2.0.3
xdebug is working; it writes to the log file.  I had it communicating
to the client before, haven't used it for a while, tried a new client
(eclipse); couldn't get breakpointing to work, decided to go back to
basics, with the command line client 0.9.0; and it just sits there,
"waiting for debug server to connect".
Yes, I've restarted apache, yes I've rebooted the machine, with all
other possible clients not restarted.  The xdebug section of phpinfo()
looks fine (see below).  All the ports should be 9000; I don't know
any other program that might be running on port 9000; I scanned the
ports and the only thing I see on 9000 is xdebug client, listening.
xdebug.remote_enable is on -- I don't know what else to do or check.
Why won't they connect???  I've spent 12 hours on this now, and I'm
tearing out my hair.  And about to throw my computer to the ground.
If anyone has any ideas, I'd be very grateful.  Is there any way I can
sniff for xdebug; debug xdebug?

Differences: I am on Windows Vista, PHP is 5.2.6. There is one reply
in the archives, which says that autostart is off and that therefore
XDEBUG_SESSION_START=1 (or similar) must be appended to the URL in the
browser. I don't know about the original poster, but I am doing that.
Below you find my xdebug settings from phpinfo:
