Can we install Exchange 2003 on Windows 2003 SP2 64 Bit Edition?

Hi,

Can we install Exchange 2003 on Windows 2003 64 Bit Edition?

I have gone through link : http://blogs.technet.com/b/exchange/archive/2005/07/11/407529.aspx and mentioned as,  Exchange 2003 cannot be installed on Windows 2003 64 Bit.The major reason for this limitation is that the Installable File System (ExIFS) driver runs under 32-Bit Kernel mode. Exchange Server 2003 doesn't include an Installable File System (ExIFS) 64-Bit driver version.Running 32 Bit Kernel mode drivers under 64 Bit Windows 2003 is not supported.

Please help me.

Thanks,

Sudhir
