PHP header and odbc struggle with MS-SQL 2003...

Any success with making the PHP Header and PHP odbc_connect work successfully on PHP version 4.0.2 while the IIS 5.0 is hooked up to MS-SQL 2003? We had no problem with this if IIS 5.0 is hooked up to MS-SQL 2000. I assumed it had to do with the PHP depending on the named-pipe. I just switched the ODBC driver over to TCP/IP then all of a sudden, errors with PHP Header and PHP odbc_connect. Problem is force.cgi-redirect doesn't exist on PHP 4.0.2. But PHP ODBC have problem with MS-SQL 2003 because it's a little different. Yea, we know we need newer PHP version, I already have most of the website working on the test machine with the newer php version except a few more websites that have yet to be upgraded to work with newer version. Thanks, Scott
