Eror: call to undefined function - suspected brain dead user!!

Besides the obvious problem of running a win32 environent. I am trying to get this current combination working. ---- machine 1 running: Win2K Server - IIS5 - php 4.06 - MSSQL Client Tools Machine 2 running: MSSQLServer ---- The error message i am getting is: "Fatal error: Call to undefined function: mssql_connect() in D:\dcl\mssql.php3 on line 68" Now i have followed the php docs and user suggestions. PHP is definately working. I have set php up as an CGI executable. And the function phpinfo() works like a charm. I see no reference to MSSQL support in the returned page from phpinfo(). What steps do i need to take to ensure that i am loading the php_mssql.dll properly.? I have seen reference to "placing the .dll in the same directory as php.exe" "putting it in the system32 directory" "leaving it the extensions directory and editing the php.ini file" I am now thoroughly confused and would love a couple of pointers to some accurate info. Thanks in advance, ram. ps. dcl is a php app called Double choco latte, http://dcl.sourceforge.net. it looks great... i just can't get it to run locally<g>
