When the app server starts, it prints the value of JAVA_OPTS, and one of those options should be -Djava.library.path="...". Make sure that the bin/native directory, and the php directory (the one that has all of the php-related dlls) are in that list. Another thing to try is open the php5servlet.dll with the depends utility (one of the XP support tools). This utility will chase down the dlls on which php5servlet depends to ensure that all of them are in the PATH (for me it says that dwmapi.dll is missing, but apparently it is not needed).
