On the system that I am having the operating system is the Windows 7 64 bit and that to it is the Home Premium. Now I want to know if there is way to change my 64 bit Windows to the 32 bit. I want to do this because I want to connect remotely to the Exchange2003 Server and Windows2003 authentication. The problem that I am facing is that I am unable to hook up from my windows7 Home Premium 64bit laptop. Can you all please suggest me something?
