When using "The FastCGI Technical Preview 2" for IIS 6, the debugger does not work. When I switch back to plain CGI, it works fine. I have the PHPEd 4.6.3 Build 4633.

Here is what the debugger tells me:
---------------------------------------------------
DBG 3.1.7

Failed to run DBG session

Reason: client ip address [(null)] lookup failed
Not sure what it means? Visit http://www.nusphere.com/dbg/ for troubleshooting.

Debugger request: "36693869;d=0,p=1,c=0"
Request found in: "$_COOKIE['DBGSESSID']"
Target PHP version: "5.2.0"
Server API: "CGI/FastCGI"
Extensions API: "220060519"
Modules API: "20060613"
PHP API: "20041225"

4633 comes with dbg 3.1.9, not 3.1.7. You may want to update debugger modules you installed on the server.
You may also want to check if 'REMOTE_ADDR is populated in the phpinfo().

I downloaded 4633 today from My NuSphere > My Products. It comes only with PHP 5.1. So I also downloaded PHP 5.2.1 from My NuSphere > My Updates. The file name was suprisingly NuSphere-phped-4.6.2-php5.2.0-Win32.exe and it really installed only PHP 5.2.0 with DBG 3.1.8.

What am I doing wrong? Where can I get PHP 5.2.1 with DGB 3.1.9? Why it's not embedded in the 4633 install file? Thanks.

this page http://www.nusphere.com/download.php.ide.htm contains proper link to php5.2.1:

I have got 5.2.1 with dbg 3.1.9. When debugging under the fastcgi it fails as before:

_SERVER["REMOTE_ADDR"] = 127.0.0.1

you need to turn off auto_globals_jit in php.ini

It works. Thanks.
