Hello
I have ASP files in one web server and dll's in vb6 that connects to sql in another server.
I would like to know if there are needed any specified component in order the application, asp pages that call a main dll that references another dll's and that connect to sql to obtain data to be showed in excel, works ok; The application tested in a local machine works fine, but not in the server, maybe the server needs to have installed something different from com+, or mowc or mdac, in order to don't obtain the error message http 404, file not found.
The asp are in a server, and the dll's and the sql database in the other server.
Anybody could help me with this?
