Hi there I have an ASP application running on Windows 2003 Server. This application need 'ADsSecurity.dll' registred to run. Now I would move this to a new server, which is a W2k3 64-Bit server. Now I have tried to register the dll. But there is an error message (LoadLibrary("ADsSecurity.dll") failed - The specified module could not be found.). Wehre is my problem? Is it possible to install 'ADsSecurity.dll' on a 64 bit system?
