I am trying to connect over the network to an SQL Server database. There is no Instance Name associated with the database. Using SQL Server Authentication (with a different login from my network login) I was able to connect.
I am using: SQL Server 2005 (188.8.131.52) SQL Server Driver for PHP (Version 1.0) PHP 5.2.9-2 Apache Web Server Version 2.2.11
Laptop: Dell Latitude D820 running Microsoft Windows XP Professional version 5.1.2600
By default, the SQL Server Driver for PHP uses Windows Authentication to connect to SQL Server.It is important to notice that in most scenarios, this means that the Web server's process identity or thread identity (if the Web server is using impersonation) is used to connect to the server, not an end-user's identity.
It sounds like this might be the problem: There isn't a login on the server for the identity being used to establish the connection. I'm not sure how to change Apache's process identity, but I'd start investigating there. Or, you could try SQL Server Authentication: How to: Connect Using SQL Server Authentication.
Hope that helps.
