cannot find file always

I had a problem with some database hosted on IIS server. Some files connected without problem, some dont, some little do - little dont.

It was my first time to deal with IIS server, so I noticed some strange things when using include functions.

I resolved problem like this: I fixated $dsn (path) in class itself, using command from class ODBC_Conn and didnt have any more problems.

$dsn = str_replace("/", "\\", $_SERVER["DOCUMENT_ROOT"]) . "\\" . str_replace("/", "\\", 'path/database.mdb');

If somebody could tell some better way, or to point out what should be considered when using this class (since I'm no expert), would be thankfull!
