Since the --with-eaccelerator-info is on by default it should be set in my download at: http://www.sitebuddy.com/PHP/Accelerators/eAccelerator_windows_binaries_builds

Yes your eaccelerator.allowed_admin_path looks correct.

Make sure you have the extension loading the proper filename.
If you did not rename the download:
extension="eAcceleratorCVS_5.1.4.dll"
If you did rename it eaccelerator.dll:
extension="eaccelerator.dll"

Also make sure that file (eaccelerator.dll or eAcceleratorCVS_5.1.4.dll) is in your PHP extensions folder as defined by the variable extension_dir in your php.ini.

Good luck,
