Help w/ SQL Server 2k install for connecting with PHP

Hi, I just setup SQL Server 2k on my machine (XPpro) and I am trying to connect to the database I set up .. with PHP but I am getting this errror: Warning: MS SQL message: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. (severity 14) in c:\apache\htdocs\iabol_quebecor\dbcon.php on line 2 Warning: MS SQL: Unable to connect to server: aeon in c:\apache\htdocs\iabol_quebecor\dbcon.php on line 2 Can't connect to AEON Now, I set up the standard user as sa with blank password on my machine for testing but it is not working. I am not incredibly savvy with SQL Server as I should be by now. I haven't worked with it in a couple months. So, does anyone have an idea what I need to do to the SQL Server configuration to get it working? The agent is running, mssql.dll is enabled in php.ini, etc. It must be some security setting I need to fix. Any suggestions?? Many thanks! Nicole www.aeontrek.com
