Windows Authentication not being impersonated - Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

[benphp]

PHP v5.2.17

IIS v7.5

 

I have a script that hits a MS SQL db that is authenticated via Windows. If I run the script on the local server (localhost for example), it recognizes my Windows logon and passes the logon to MS SQL Server and all is well.

 

However, when I run the page from another PC, the script fails with: "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON' ".

 

I have the page Authentication set so Anonymous Authentication is Disabled, and Windows Authentication is Enabled. This is the correct setting. I know. So why is it that the server isn't authenticating me via the web and passing along the authentication "impersonating" me for MS SQL?

 

 

I've tried setting fastcgi.impersonate to 0, but that doesn't help at all. Here's my PHP.INI settings:

default_socket_timeout = 60
upload_tmp_dir="C:\Windows\Temp"
session.save_path="C:\Windows\Temp"
error_log="C:\Windows\temp\php-errors.log"
cgi.force_redirect=0
fastcgi.impersonate=1
fastcgi.logging=0
cgi.fix_pathinfo = 1

Any tips, help appreciated!
