So, many kudos to Matt Small for spending at least 30 minutes, uncompensated (mostly - beer or wine will be paid!!) with us on the telephone, and applying significant Windows/IIS/.NET/CF knowledge to getting this working.
We are currently working with .NET 2.0 and CF8 running on IIS 6.0 in 32-bit mode on a 2003 Windows 64-bit server. Part of the problem appears to have been with the CF8 installation, which did not give the IUSR_xxx accounts permission to access the COLDFUSION8 file directors, and caused ACL errors when attempting to access web sites. When these permission were manually added to the CF8 directories, everything seemed to have started working ok. Again, many thanks to Matt Rick Colman ".NET will only run in 64-bit mode IIS" That's simply incorrect. Install .NET v2.0 on x64, then change the bitness of IIS in the metabase: c:\inetpub\adminscripts>cscript adsutil.vbs set Enable32BitAppOnWin64 true Then install .NET on IIS: c:\windows\microsoft.net\framework\v2.0.50727>aspnet_regiis -i That will run 32-bit .NET on a 32-bit IIS worker process on Windows Server 2003 x64. - Matt Small ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:301711 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
