    Hello,

    Thanks for your post. For ASP.NET questions, it is best to ask in http://forums.asp.net/.

    Here are some information searched from web that might be useful for this issue.
    According to this KB: http://support.microsoft.com/kb/894435, following are prerequisites to running ASP.NET 2.0 on IIS6:

    1. Installed .NET Framework 64-bit version
    2. Enable IIS to support 64-bit:
    cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0
    3. Register ASP.NET 2.0 x64 to IIS:
    %SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
    (You don't need to change any code or project settings)

    By running web app in 64-bit, it can take advantage of the full memory address space of new 64-bit processors and servers.
