上传php5.ini后，出错，能否恢复未传php5.ini之前的配置？

david803

godaddy的windows 150G无限制的主机，上传php5.ini后，出错了，删了php5.ini，错误提示还是刚才的错误不变，我重启了IIS N遍也没用，请问能否恢复到未传php5.ini之前的默认配置？
我未传php5.ini，我的php程序是可以正常执行的，一切正常的，但是，我，手有点点痒痒的，看到很多大侠都设置了自定义的php5.ini，我也从论坛上copy了一份，传上去（网站的要根目录上），结果，出错了：
Warning: file_get_contents(D:\Hosting\6041488\html\_coolandcold/tmp/inc/nav_all) [function.file-get-contents]: failed to open stream: No such file or directory in...
file_get_contents不正常了。
我的php5.ini内容：
register_globals = On
allow_url_fopen = On
magic_quotes_gpc = On
memory_limit = 50M
max_execution_time = 120
max_input_time = 60
post_max_size = 8M
file_uploads = On
upload_max_filesize = 192M
extension_dir = "c:\php5\ext"
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_pdo_mysql.dll
extension=php_gd2.dll
extension=php_sockets.dll
extension=php_mbstring.dll
session.save_path = "d:/temp/tmp"
session.use_cookies = 1
session.name = PHPSESSID
session.auto_start = 0
;session.cookie_path = /
session.serialize_handler = php

请问能否恢复到未传php5.ini之前的默认配置？
