Xdebug not as zend extension IIS7

Question

I can't get xdebug loaded as Zend extension, because the php.ini automatically puts in the wrong term.

The message in phpinfo() is

XDEBUG NOT LOADED AS ZEND EXTENSION

I'm Using IIS 7.5 on Windows Server 2008 R2 Enterprise PHP 5.3.8 Zend Engine v2.3.0

My part of php.ini:

[xdebug]
zend_extension=php_xdebug-2.2.0-5.3-vc9-nts.dll
xdebug.remote_enable=1
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"

No errors logged.

I need to activate every extension in IIS settings. When I then restart IIS, php.ini is updated with the line

[PHP_XDEBUG-2.2.0-5.3-VC9-NTS]
extension=php_xdebug-2.2.0-5.3-vc9-nts.dll

Why this?

The OP wrote:

It now works after changing the extension path to absolute. The 2 lines were added anyway, but phpinfo() now shows the full xdebug config.

Working part of php.ini:

[PHP_XDEBUG-2.2.0-5.3-VC9-NTS]
zend_extension="C:\Program Files (x86)\php\ext\php_xdebug-2.2.0-5.3-vc9-nts.dll"
xdebug.remote_enable=1
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"
[PHP_XDEBUG-2.2.0-5.3-VC9-NTS]
extension=php_xdebug-2.2.0-5.3-vc9-nts.dll
