SQL Server Connect Issues

First, I will admit that I am new to PHP. I'm installing PHP on our Windows 2K / IIS server for some users who want to use it. We also host SQL Server 7 for websites. I'm getting the following error on the server, and on the client's webpages: PHP Warning: Unknown(): Invalid library (maybe not a PHP library) 'msql.dll' in Unknown on line 0 Here is what I have done so far: - I originally installed PHP 4.3.3 on the server using the Windows Installer version. - Uncommented out the extension=php_mssql.dll line inside of the php.ini file. - Figured out that I needed to download the extensions since they weren't included in the Installer version. - Added all of the php_*.dll files to the same directory as the PHP.EXE file. (I've also tried putting these in the WINNT\System32 directory, with the same luck.) - Made sure the msql.dll file is in the same directory as the PHP.EXE file. (Again...tried in the WINNT\System32 directory.) - Made sure the ntwdblib.dll file was in the same directory as the PHP.EXE file. (As above...tried the WINNT\System32 directory.) Originally, I was having problems with an error about the msql.dll file not being found. Once I had it put into place, then the current error message came about, and I have not been able to get it to go away. I've tried about everything I could find on the Internet about this type of error. The strange thing is that it appears to be talking to SQL Server just fine, since the PHPBB program I also installed for one user connected to the database at least long enough to create all of the tables and fields required in the install.php file. I keep seeing information about having to recompile the PHP.EXE with certain settings using FreeTDS, but from what I have gathered, that is only required if running on Linux. (Right??) Any help anyone can give me would be great. Thanks, ~ Tom
